The most cursory assessment of news and events around the globe during this first decade of the Twenty-First Century leads to the inescapable conclusion that we live in perilous times. Confidence remains high that the United States military can and will defend America from a missile attack originating outside the country. Looking back to that fateful day in September 2001 and realizing the magnificent job local, state, and federal officials in New York did in managing the World Trade Center crisis makes one feel proud. The detonation of a nuclear device in or above the Earth’s atmosphere produces an intense, time-varying electromagnetic field (electromagnetic pulse or EMP). Obviously, the HEMP shield and all POE protective devices are hardness critical items (HCIs).
Generally, HEMP facilities are specified as welded systems by the military to be installed during the initial building stage.
Present shielding technology can be used to protect existing Regional Emergency Management Control Centers (REMCCs) or the combined regular and emergency communications facilities from the effects of EMP.
To protect the overall functioning of an emergency system, the vital equipment linking first responders to the command system must be shielded as well.
As standard operating procedure (SOP) as defined by the user, members of mobile units at the fire or police precinct could exchange the emergency walkie-talkie radios in their vehicles with freshly charged units at the fire house or police precinct every 24 hours, or as necessary. While the goal of achieving a cost-effective shielding solution may begin with a consideration of the attenuation characteristics of the shielding material, once a decision regarding all-welded steel vs.
Once a material and construction type has been chosen, shielded doors become the most critical component in the system. Accessories are needed to transmit power and signals, HVAC, liquids, or gases into or out of a shielded environment. As a minimum at the time of acceptance, all shielding systems should be tested to confirm shielding performance in accordance with MIL-STD-188-125-1 and -2. One of the critical problems with the use of a shielding system is the lack of any clear-cut understanding of exactly who is responsible for maintaining the integrity of the system. Absolute performance and reliability of a shielding system is essential in times of emergency. When emergency responders enter large structures (such as apartment and office buildings, sports stadiums, stores, malls, hotels, convention centers, warehouses), radio communication to other responders on the outside is often impaired.
The National Institute of Standards and Technology (NIST) is involved in a multi-year project to investigate wireless communications problems faced by emergency responders (firefighters, police, and medical personnel) in disaster situations involving large building structures.
The work has involved collecting a large body of open-literature data of quantities used to assess wireless communication channels. Because lives may be at stake in emergency response scenarios, a higher standard for reliability of service must be applied compared to those that might be deemed adequate for commercial applications. A recent study reveals radiation from solar events is unlikely to affect earth & the dose of radiation emitted during the events isn’t enough to harm people. Air Force EMP Weapon Revealed – What If The Enemy Uses The Technology On US Power Grid? An Air Force EMP weapon that uses electromagnetic pulses to both target and destroy a€?digital weaponsa€? is in the works. The Air Force EMP weapon is called CHAMPS a€“ or Counter-electronics High-powered Microwave Advanced Missile Project.
Disasters Most Governments Are Not Prepared For Still Secret and Secure, Safe Rooms Now Hide in Plain Sight Egg Shortage Caused By Bird Flu Baltimore Shootings Skyrocket, Mayor Blames Police? This article presents some methods of EMP (electromagnetic pulse) protection for facilities.
This article provides the least expensive EMP protection process for the massive residential USA population since retrofit protection of existing homes is expensive. To be optimized along with cost and lifestyle are security, attainability and some ways and means. Since EMP protected solar rooftops, plus batteries, is the heart of available electricity, the Solar rooftop folks have joined the EMP and EMC community to make an EMP-EMC solar joint venture (Figure 1).
Following an EMP incident (Figure 2) comes immediate local replenishment shortage (store shelves quickly raided and stripped). Peripheral electronic security walls take on creative means and residents can enjoy their vegetable gardens. Because vehicles are mostly inoperative following an EMP event, bicycles with container carts and protected electric golf carts are the preferred modes of transport out to the country cottage-shed locations. A cottage shed is defined as a small detached shed, configured into a liveable home with its own solar rooftop.
A somewhat expanded version of Figure 3 to accommodate an automobile and a golf cart, plus more storage space is shown in Figure 4. Shown in Figure 5 are samples of cottage sheds before solar rooftops and EMP protection are added. The above construction of the later-to-be-added solar rooftop is in fact only partly added at the end of construction.
The foundation and rooftop become the challenge since they have several penetrations as shown in Figure 7. A second solar cell generation, thin film, Cadmium Telluride, CdTe, is gaining popularity for solar and now represents about 25% of the installations in the US. For EMP protection, it is logical that each panel have a 30 OPI shield screen built in for quality control and cost reduction. Finally, a top screen to cover solar panels, interconnecting wiring and micro-inverters, is used. The rated power output corresponds to the solar panel exactly pointing to (perpendicular to) the unobscured sun at high noon=a condition that rarely exists in parts of the US.
Knowing the power consumption of all the appliances and approximate use times allows the assignment of loads plus allowing some of the energy for battery charging.
Once an EMP protected installation is declared to be finished, it is time to verify EMP protection compliance by on-site testing. The test configuration is first calibrated to form a reference with both transmitter and receiver configurations located on the outside (step 1). The tests are repeated for the other remaining three sides of the building, recording the shielding effectiveness of each side for all seven test frequencies. While the building EMP and Solar EMP compliance tests can be done simultaneously, in the early stages, it may be best to do each separately.
As EMP survivalists learn they can live better in larger EMP protected communities, they will form such communities. The above conceptual development is partly protected from outside intrusion by an electronic wall with proximity alarms surrounding the facility. Timely spoilable replenishments are a major problem following an EMP disaster, since the site may be several hundreds of miles to the nearest non-EMP sources. The above concept invites other real estate entrepreneurs or some large corporations to establish their own development with completely EMP protected facilities.

The nation has an extensive missile defense program, a legacy of the Cold War era; and the government has had many years to prepare for whatever the future may hold, as well as plenty of doctrines for guidance.
These facilities include electric power facilities, oil refineries, water treatment plants, banking systems, pipelines, transportation systems, emergency facilities, and communications facilities. Imagine what might have occurred if the perpetrators of that vicious attack had included in their suicide mission the detonation of an electromagnetic pulse device that could disrupt communications of the police, fire, and medical teams responding to the emergency. The EMP environment produced by an exo-atmospheric event is caused by the sudden entrance of energy (chiefly gamma rays) into the atmosphere.
Specific areas within a facility containing critical high value hardware, software, or other equipment should be hardened to the effects of IEMI or other deleterious electromagnetic conditions.


Vital communications equipment is, of necessity, deployed throughout the community when emergency strikes. Today’s shielding industry produces small copper enclosures fitted with shock mounts that can be installed in all mobile field units. Similarly, ambulance crews could have an alternate exchange point at a local hospital or other appropriate location. These include maintenance, installation timing and cost, life cycle parameters, and the system’s adaptability vis-a-vis a number of physical requirements. While accessories have an important impact on total system performance, their performance can be controlled by following proven techniques and by applying the appropriate design principles. Shielding effectiveness testing is generally a field test at the highest frequency of usage.
At too many facilities, there is an ongoing power struggle to shift shield maintenance responsibility from the facilities to operations department and vice versa. The key to obtaining a good shielding system is an understanding that seams, doors, and other penetrations are the critical elements that must function as a whole to create an effective shielding system.
To protect a shielded system investment, look for a full service, turn-key designer, manufacturer, installer and tester of shielding systems with years of experience in the military and government arena and a strong background in the EMP field.
Report of the Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack: Executive Report, 2004.
MIL-HDBK-423 Military Handbook – High Altitude Electromagnetic Pulse (HEMP) Protection for Fixed and Transportable Ground-based C4I Facilities Vol. Wireless communication from within large buildings and other structures can be complicated by several factors, including the strong attenuation of radio signals caused by losses in the building materials, scattering from structural features (multipath), and the waveguiding effects of corridors and tunnels.
The work, funded by the Justice Department’s Community Oriented Police Services (COPS) program through the NIST Office of Law Enforcement Standards, has grown out of communications problems such as those encountered during the September 11, 2001, collapse of the World Trade Center in New York. To provide statistics on signal level and variability in representative environments, NIST researchers measured the received signal strength outside the various structures while a transmitter was carried throughout the interior. Boeing and the United States Air Force have confirmed that they are testing an EMP weapon that is reportedly so accurate it can target even a specific building.
The EMC (electromagnetic compatibility) community provides most of the products and know how for structure shielding, bonding and grounding, plus cabling and connector surge suppression along with filtering. This is partly because the government, at all levels, is perceived to have abdicated their fiduciary protection responsibility.
This article outlines how the venture is accomplished as a county mission objective for most of the 3,141 counties in the US. In many cases, these real-estate developments are housed on farmers’ properties that already enjoy the right settings. This sequence results from the choice of materials, how shield portions are bonded; special treatment of roofs, vents, siding windows and doors and foundations. The reason is that the solar panels and micro-inverters are encased in their own screening mechanism and require that a bottom shield be added before the solar rooftop is installed. This procedure may be abandoned by 2016 when built-in solar panel shielding becomes commercially available. Tests are made at the seven test frequencies (1MHz–1 GHz) as shown in Table 3 (obtained from the Fourier Transform of the EMP pulse waveform threat), and the RF attenuator settings recorded. Then, for each of the seven frequencies, the corresponding four side shielding effectiveness are compared and the smallest value (least shielding) is selected. The right side of the Figure 10 contains an owners’ common area for entertainment and some vitals storage and replenishment. Thus, for larger developments, or for one per average-size county, a relatively inexpensive 4,000 ft (1,200 meter) mat-lined, dirt runway is installed. This paper does not discuss the capabilities or readiness of the United States military or that of its allies, nor does it focus on developing effective standards for first-responder communications both inside and outside challenging environments such as skyscrapers and tunnels.
Most critical infrastructure facilities depend upon electrical and electronic systems to function. When such an event takes place above 30 km, it is defined as a HEMP (high altitude electromagnetic pulse) effect and can affect a vast area. Creating an electromagnetic barrier that will prevent or limit HEMP or localized EMP fields or conducted transients from entering the shielded area is primary.
Smaller facilities, upgrades or retrofits may involve other forms of shielding, particularly modular shielded panels. These modular systems can be installed within an existing facility to meet the dimension and operational needs of a particular entity.
The equipment of first-responders could be damaged or rendered totally inoperable during an initial surge.
These shielded boxes will exceed the MIL-STD-188-125 performance requirement and will protect field radios from electromagnetic pulse (Figure 4).
Those radios in need of recharging could be placed in a secure shielded enclosure with a battery charging system. As noted above, typical shielding system construction choices include welded steel rooms or buildings, modular systems made of galvanized steel or copper-clad panels, and modular pan form designed systems for retrofitting or for establishing shielding within an existing facility. While fewer seams would logically mean less potential for degradation, it is seam quality that is absolutely vital.
To preserve the integrity of a shielded enclosure, doors must include a durable means for making repeatable seals around their entire perimeter.
Necessary penetrations that do not compromise shielding effectiveness can be achieved by using a combination of power line filtering combined with ESA and MOV (metal oxide varistor) protection or with waveguide below cut off and fiber optic concepts (Figure 8).
Unfortunately, without clearly defined responsibility for preventative maintenance, shield integrity will diminish rapidly.
It is the design of the shielding system and the quality of the installation that will determine its long-term reliability. Insist on seeing test reports from previous installations that document the vendor’s ability to provide a reliable shielding system. The researchers also collected data on the level of reflectivity (multipath) a signal encounters as it travels from within the structure to the outside. The experiments were carried out at emergency responder frequencies to gather germane and useful data for those developing and assessing new technologies and creating standardized test methods within the context of the unique needs of the emergency response environment.
Air Force EMP weapon would reduce an enemya€™s high-tech weapons to nothing more than a heap of metal if hit with an electromagnetic pulse a€“ the same is true for effect on American weapons should an enemy possess the same technology.
They also provide the service for on-site compliance testing of an EMP protected installation. EMP survivalists and preppers have independently moved forward to cover some of the protection gap.
They must have a survival location out in the country since it is perceived that fellow man will steal and kill for water and food. They all contain ponds so that most part-time residents can enjoy waterfront, if one is available. For example, generate a group of five: from the county Economic Development office or County administrator, Chamber of Commerce, an engineer or architect, a member from the pragmatic EMP survivalist group, plus a secretary.
Generators have limited value as they require fuel which is likely not to be available for long periods of time following an EMP incident. Note the A-frame designed to maximize solar rooftop power output in more northern latitudes so that roofslope more nearly equals site latitude. For example, the popular to be, 30 OPI (openings per inch) shielded metal screen is laid down and overlapped under the concrete footing rebars. Waveguide beyond cutoffs are used for vent pipes and water and sewage handling as shown in Figure 7. Their DC output is converted to AC via an inverter located near the main power distribution panel.
Meanwhile, EMP protection is made available by first laying down a screen over the asphalt shingles and then applying the panel racking. The flat roof structure will accommodate 18, 3ft x 5ft panels in a 3 x 6 array, The rating of the solar panel manufacturer is 225 watts per panel. It contains an RF scanning oscillator or sweeper which feeds a power amplifier that drives radiating test antennas pointing at the building to the right.


Then, maintaining the same distance between transmitter and receiver, both are moved as shown in step 2 with the receiver configuration moved to the middle of the building and attenuator settings again recorded to get the same received levels. This is a fraction of the cost to EMP protect (retrofit) an existing home with solar panels along.
These systems can be susceptible to a little known, yet significant and growing threat, the radio frequency weapons mentioned above. The sudden inability of the mayor and other city government officials to mobilize resources during such a chaotic event could be catastrophic. Detonation of a weapon at lower altitudes will produce an electromagnetic pulse that may be less intense, but will still be strong enough to induce fields that can cause critical systems in a smaller more localized area to malfunction because of circuit damage (Figure 1). The shield and all points of entry (POE) must be treated properly to maintain shield integrity. Items such as shielded vestibules with interlocked doors, waveguide honeycomb vents, various pipe penetrations, power and signal line filters with surge protection (electronic surge arrestors or ESAs), and fiber optic penetrations are all HCIs—individually or as part of an assembly.
Industry standard modular shielding systems are available in single-shield copper or steel, double-layer steel cell type, or steel pan form enclosures and are easily installed in existing facilities needing HEMP or EMP protection.
Fire houses, police precincts, hospitals, fire trucks, police cars, and ambulances are all vulnerable to electromagnetic pulse. Since radios are a high cost item, the recharging stations should be in tamper-proof security containers (Figure 5). Pin-pointing any possible weak links during the design stage of a shielding system helps to assure reliable performance after procurement. An analysis of shielding alternatives indicates that some seaming techniques require fewer seams per shielding surface area. Shielded door performance should provide a safety factor of up to 20 dB both initially and after a reasonable number of cycles for all requirements up to 100 dB at 10 GHz. Signal line interfaces, penetrating the shield, should use a fiber optic system for optimum EMP security. Even when a problem is finally noticed, there is a tendency to resort to untested, “band-aid” or quick fix solutions. In many cases, single-shield, “Pan Form” modular steel, double-shield galvanized steel cell-type panels, or a lightweight 12 or 24 ounce copper system can provide a reliable, cost-effective solution for EMP applications.
However, there results a post-EMP era of bare bones survival lifestyle is sacrificed after an EMP event. County community, cottage-shed developments also provides an excellent weekly escape for many. They create, generate and use educational and training materials and programs, establish plans and timelines and help make things happen. With proper bonding to the structure siding, the foundation is thus shielded with no discontinuity among seams. Sometimes, micro-inverters are used, one at each panel output and the AC outputs are combined in parallel.
The difference between the attenuator settings in step 1 and step 2 constitutes the building RF shielding effectiveness in dB for the test frequency. As the EMP threat becomes clearer, homeowner associations members may develop a community of cottage-sheds within, perhaps 50 miles or closer to their main residence. This increases at an accelerated rate as more of the remaining 80% of the American families move toward their week-end country, EMP protected retreat. RFWs have already been used to defeat security systems, to disable police communications, to induce fires, and to disrupt banking computers.
At present, homeland security, some local law enforcement agencies, and border patrol resources have been stretched extremely thin. Another form of attack, intentional electromagnetic interference (IEMI), has been defined as the “intentional malicious generation of electromagnetic energy introducing noise or signals into electric and electronic systems, thus disrupting, confusing, or damaging these systems for terrorist or criminal purposes.” Nature’s contribution, lightning EMP (LEMP), like HEMP and other forms of EMP, involves a brief but intense electromagnetic disturbance in the atmosphere and thus presents another potential threat to the operation of electronic systems.
Retesting should be an annual scheduled requirement—a fail-safe measure that will detect any problems before system failure occurs and thus assures ongoing EMP protection. These solutions may satisfy the primary objective of meeting shielding requirements temporarily, but may not provide an adequate factor of safety to assure long-term reliability. This article shows how a post-EMP era can economically protect and retain most of ones’ lost lifestyle.
Real estate developers help make it happen and counties make pragmatic administration and financing possible. This is enough for heaver loads like outside wall-mounted air conditioners, washer and dryers and hot-water heater. The power-line and telephone bottom entrances and water line and sewage lines are specially treated.
Many of these devices are small, suitcase-sized or slightly larger devices that could be smuggled into the country the same way drugs and other contraband penetrate our borders and become available on the black market. Unfortunately, they are not credited for deterring potential attacks as much as they will be remembered for the one they did not. Still, to achieve the most reliable shielding system, it is always good policy to minimize penetrations and seams. In contrast, the standard “Double Electrically Isolated” (DEI) construction requires two seams per joint. The industry standard RF door most suitable for modular cell or pan form enclosures is the Single Knife Edge (SKE) door (Figure 7). They also swap their findings, plans and actions with neighboring counties and their state on a timely basis.
In today’s world, weapons of mass destruction (WMD), so called “dirty bombs”, radio frequency weapons (RFW), and intentional electromagnetic interference (IEMI) devices can generate localized electromagnetic pulse surges to disrupt everyday services. These devices in the hands of a terrorist are capable of inflicting extreme damage and may be capable of generating a localized intentional EMI disturbance at any location. This premise underlies a useful management philosophy that can be applied throughout the shielding system selection process. Martin has continued to lend his expertise to the company’s RF shielding systems for government and commercial industries requiring protection from critical EMP and IEMI.
Becquet, “Attenuation of Radio Wave Signals Coupled Into Twelve Large Building Structures,” Natl.
Consider these key factors affecting modular shielding system performance—material characteristics, quality of seams and penetrations, door performance, accessory performance, and the quantity of seams and penetrations. Generally, two layers of shielding are used simply because seam quality makes it difficult to achieve the shielding objective with just one layer of shielding.
The SKE door can be set up for semi-automatic operation with a door interlock system that prevents both doors from being opened at the same time.
