The weapon in question: Boeing's "CHAMP," short for Counter-electronics High-powered Microwave Advanced Missile Project. CHAMP carries a small generator that emits microwaves to fry electronics with pinpoint accuracy.
What makes CHAMP even more interesting is that, unlike a nuclear electromagnetic pulse weapon, which fires once, blacking out entire nation-states, CHAMP can fire multiple times, pinpointing and blacking out only essential targets. This would permit, for example, taking down radar defenses in a hostile state, while saving the electrical grid that supports the civilian population.
Boeing headlines the CHAMP product, but at least two other companies are known to be involved in the project. Raytheon's involvement shouldn't come as a surprise, given the company's expertise building complementary weapons, such as its MALD-J radar-spoofing, electronics-jamming drone.
A cruise missile with an estimated range in excess of 600 miles, JASSM-ER will itself be deployable from combat aircraft such as F-15 and F-16 fighter jets, B-1 and B-52 bombers, and the F-35 stealth fighter -- extending CHAMP's reach even further. To date, Military Embedded Systems notes that the Air Force Research Laboratory has contracted Boeing to build only five CHAMP devices. From MALD-J radar-jamming drones to Switchblade kamikaze guided rockets and now CHAMP mini-electromagnetic-pulse weapons, the Air Force seems intent on fighting its next war more or less entirely by remote control. To the extent CHAMP makes that easier for them, I expect it to be a very popular product indeed. Although single cycle pulses based on photoconductive antennas or optical rectification techniques have been available for almost three decades, only recently pulse energies exceeding one micro-joule have become available on tabletop systems.
Oak Ridge National Laboratory maps the areas likely to be blacked out in the event of a high-altitude nuclear EMP attack on the United States.
The EMP was powerful enough to affect the electric grid in Hawaii, blowing out streetlights, and resulting in telephone outages and radio blackouts. Graham then went on to become one of the nation’s leading experts on the topic, helping advise on both defensive and offensive capabilities.
We needed to protect our ballistic missiles, B1 bombers, and communications systems for command and control. More recently, he has shifted his focus to protecting against what he now sees as the potentially greatest existential threat to the United States: an EMP attack against our civilian infrastructure – particularly the electric power grid. To that end, Graham has served as Chair to both the 2001-4 and 2006-8 Commissions to Assess the Threat to the United States from Electromagnetic Pulse Attack, and was a member of the Department of Defense’s Science Board and the National Academies Board on Army Science and Technology. Since then, there have been an enormous increase in our dependency on electronics, computers, and microelectronics. Graham expressed concern that Iran also has this offensive capability within their arsenal, and perhaps within their current military doctrine as well. We have data indicating that the Iranians have launched their versions of Scuds off of the Caspian Sea – not from land, but from the sea – and launched them over land. Here’s an excerpted summary from the 2008 Report of the Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack that would make great science fiction.
The electromagnetic pulse (EMP) generated by a high altitude nuclear explosion is one of a small number of threats that can hold our society at risk of catastrophic consequences…A single EMP attack may seriously degrade or shut down a large part of the electric power grid in the geographic area of EMP exposure effective instantaneously. In fact, the Commission is deeply concerned that such impacts are likely in the event of an EMP attack unless practical steps are taken to provide protection for critical elements of the electric system and for rapid restoration of electric power, particularly to essential services.
It goes on to note that we have become so efficient, technology-dependent, and highly leveraged that utilities would lack sufficient trained service personnel to address a disaster on this scale. The International Electrotechnical Commission defines three components associated with a nuclear electromagnetic pulse: E1, E2, and E3. One curious facet of an EMP event is that we wouldn’t even feel it pass through our bodies. We would have little idea of the dread potentially awaiting us, because there would be no communications.

An electromagnetic pulse device having a conductive coil, and optionally a conductive core disposed within the coil and spaced apart there from. Kopp, “A Doctrine for the Use of ElectroMagnetic Pulse Bombs (Revised Draft of RAAF APSC Working Paper #15, Jul. FIELD OF THE INVENTIONThe invention relates to electromagnetic pulse devices.BACKGROUND OF THE INVENTIONAn intense electromagnetic pulse (EMP) of short duration produces a strong electromagnetic field surrounding the pulse source. This is a higher frequency than the MHz frequency produced by traditional explosive material-containing EMP devices. To optimize the performance of the inventive EMP device, numerous parameters may be varied. The US military has been developing next generation weapons for years, and in that effort, it’s made some impressive advances.
That’s short for electromagnetic pulse, a phenomenon that can exist naturally, wherein a short burst of electromagnetic energy can overload and knockout electrical circuits. Focusing that EMP to create electrical damage without structural damage has long been a goal of the US military, which has achieved varying degrees of success. Known as CHAMP, or Counter-electronics High-powered Microwave Advanced Missile Project, the Pentagon’s project would allow the Air Force to remotely cut power to specific targets from long-range, without causing any structural damage or physical injury to anyone inside. Slated to be in operation by 2022, this project is really just a scaled-down version of a weapon which already exists onboard the USS Ponce. A novel method of hydrogen generation by water electrolysis using ultra-short-pulse power supply is demonstrated.
Air Force confirmedA last week that it's developed an electromagnetic pulse weapon of its own, and that Boeing (NYSE:BA) is helping to build it. It's essentially the old nuclear electromagnetic pulse weapon that we used to worry so much about -- but without the nuclear part. It targets not nations or cities but individual buildings, blacking out their electronics rather than blowing up physical targets (or people).
In a 2012 test flight in Utah, a single CHAMP was reported to have blacked out seven separate targetsA in succession, in one single mission. According to Military Embedded Systems, it's actually Raytheon (NYSE:RTN) that builds the electronic innards of the device -- the "shooting end" of a weapon that doesn't actually shoot anyone. But the trend in Pentagon acquisitions projects suggests the Air Force could soon be building these weapons en masse. For a continuous laser beam, a small voltage is measured across a crystal with susceptibility χ.
Ideally, the newly generated THz radiation should propagate through the nonlinear crystal at the same speed as the femtosecond laser pulse.
The femtosecond laser pulse and the THz pulse travel at the same speed through the ZnTe crystal. William Graham was active in the follow-up to the project, working out of the Air Force weapons lab in Albuquerque, New Mexico. Graham continued to lend his expertise, and became a member of the President’s Arms Control Experts Group and Science Advisor to the President. He is concerned that in the last half century since we first became aware of this issue, our increasing reliance on electronics, and hence our vulnerability, has increased tremendously. And we’ve also seen them launch missiles that have gone up and apparently exploded near their highest altitude – when you put those two ideas together – that is an EMP attack. Because a single missile with a warhead that actually doesn’t have to be all that large, has the potential to take out the U.S.


There is also the possibility of functional collapse of grids beyond the exposed one, as electrical effects propagate from one region to another…Should significant parts of the electric power infrastructure be lost for any substantial period of time, the Commission believes that the consequences are likely to be catastrophic, and many people may ultimately die for lack of the basic elements necessary to sustain life in dense urban and suburban communities. The E1 pulse is brief, intense, and very quick (traveling at over 90% of the speed of light), and can take out computers and telecommunications equipment owing to its ability to exceed voltage limitations.
The EMP would pass unnoticed through us, even as it fried the iPhones and Galaxies in our pockets, knocked out our telecommunications system, rendered our cars and computers without the ability to function, and took out our power grid.

A particularly strong electromagnetic field can produce transient voltages on unprotected or poorly protected electrical conductors. The parameters include, but are not limited to, coil length, coil diameter, number of coil turns, component materials, component dimensions, voltages applied, and currents applied. The latest: a targeted electromagnetic pulse weapon capable of knocking out electronics without collateral damage. Lightning is one natural source of small-scale EMP, while nuclear weapons can be an artificial cause. Earlier this month, the US Air Force also announced its development of laser weapons which would be attached to fighter jets, and could one day replace traditional artillery. Known as the Laser Weapons System, it has successful destroyed practice drones in a series of tests. The ultra-short power supply consists of a static induction thyristor (SIThy) and a specific circuit which is called the inductive energy storage (IES) circuit.
We Fools may not all hold the same opinions, but we all believe that considering a diverse range of insights makes us better investors. BI Intelligence takes an in-depth look at the most important aspects, including market forecasts for commercial applications, regulatory process, and the leading players. In the limit of very short laser pulses, a very short polarization is produced that is of the duration of the pulse and has the form of the pulse envelope. This way, the THz waves add up coherently throughout the length of the crystal, leading to highest conversion efficiency.
Dubbed Operation Starfish, this exercise was part of a larger project to evaluate the impacts of nuclear explosions in space. The E2 element is intermediate in duration, lasting from a microsecond to a second after the initiation of the EMP, and is similar in its effects to lightning. A spark gap or similar device is attached to the plasma discharge devices to activate them to produce a traveling electric discharge. Such an occurrence is likely to permanently damage electrical devices or cause them to malfunction either temporarily or permanently. Additionally, the device may contain one or more superconductive components, such as, but not limited to, the coil.The inventive EMP device may further include a non-magnetic insulation component disposed around the conductive coil and plasma discharge devices. The rapid change in electric fields created by nuclear explosions would knock out power within range of the weapon, if those electrical systems weren’t already wiped out by the nuclear blast, itself.
It was found that by using an ultra-short pulse with the width of 300 ns, electrolysis takes place with a mechanism dominated by diffusion limiting process in DC electrolysis. By Maxwell’s equations, the polarization P will act as a source term, radiating off a single cycle electro-magnetic pulse in the far field. The missile, launched from Johnson Island, 900 miles from Hawaii, was armed with a 1.4 megaton warhead, programmed to explode at 240 miles above the earth. Browning on US Scientist Confirms Russian Fears Of Nibiru Planet, Could Begin to Harm Our Earth this MonthMs. The discharge creates a traveling short circuit in the conductive coil thereby compressing the magnetic field. Any device containing metal oxide semiconductors, such as computers and telecommunications equipment, is particularly susceptible to damage from an electromagnetic pulse. The device may also be surrounded by a stability-enhancing component such as a cooling device. If the laser pulse has a duration of less than a picosecond, the result will be a very short electromagnetic pulse with frequency contents in the terahertz range. By contrast, the E3 pulse is much slower, a result of the nuclear explosion affecting the earth’s magnetic field, and is very similar to the effects of an intense solar storm. Accordingly, a device generating an EMP pulse can be used to intentionally disable electronic equipment. As an example, a gas such as nitrogen, or a mixture of gases, may be used to cool or stabilize the electro-discharge device arc.Still further, a parabolic reflector may be included and positioned so that radiation is emitted from the EMP device substantially at the focus of the parabolic reflector, thereby directing emitted radiation to a limited area. What was not entirely expected was the magnitude of the resulting electromagnetic pulse (EMP).


The E3 effect of a nuclear blast or severe solar storm would be to create massive currents on power lines, which could then destroy electrical transformers and potentially impact power plants as well.
This can have military applications, but may also have other applications, particularly when implemented on a small, controlled scale.An EMP device can be fabricated by filling a metal cylinder with an explosive material.
This may be advantageous to maximize output intensity of the EMP device and to protect users or objects from its effects.The scope of the invention also includes an EMP device comprising a plurality of individual EMP devices. Each electro-magnetic device may be activated by current generated from another of the electromagnetic devices, or may be activated by another means, either simultaneously or in succession with the other electromagnetic devices. The explosive material is then ignited at one end and explodes, thereby expanding the cylinder.
It’s well within the capability of even an earlier Scud missile, of which thousands have been produced – it just has to have nuclear weapon on top (Author’s note – just this month, the ISIS paraded what they claimed was a captured Scud missile in Syria. A combination of cascaded and parallel devices may also be implemented.The present invention further includes combining an EMP device having explosive material with plasma discharge devices. In an exemplary embodiment, current generated from the electro-discharge device activates the explosive material.The invention further includes a method of generating an electromagnetic pulse comprising forming a conductive coil around, but separated from, a conductive core, applying a current to the conductive coil to produce a magnetic field, and shorting the conductive coil with a plasma discharge device.
The magnetic field is compressed by the short circuit, and energy from the explosive is transferred to the magnetic field, causing an increasing current pulse. The conductive core may be metallic for example.While the invention has been described by illustrative embodiments, additional advantages and modifications will occur to those skilled in the art. This design can create electromagnetic radiation of sufficient strength to damage electrical devices.EMP devices, such as described above, will create radiation having frequencies on the order of one MHz or less. Therefore, the invention in its broader aspects is not limited to specific details shown and described herein. Radiation at these frequencies is typically emitted in all directions and cannot be focused on a specific target. Modifications, for example, to the number of plasma discharge devices and the specific configuration of the electromagnetic device components may be made without departing from the spirit and scope of the invention.
In addition, the explosion required to initiate the electromagnetic pulse can cause significant damage.
Accordingly, it is intended that the invention not be limited to the specific illustrative embodiments, but be interpreted within the full spirit and scope of the appended claims and their equivalents. Therefore, a need exists for an EMP device capable of producing radiation that does not require explosive material, that is not susceptible to premature destruction and that can produce radiation which can be directionally controlled.SUMMARY OF THE INVENTIONAn EMP device is disclosed. The device includes a conductive coil, and optionally a conductive core disposed within the coil and spaced apart therefrom.
3 depicts circuitry for an electromagnetic pulse device according to an illustrative embodiment of the invention.DETAILED DESCRIPTION OF THE INVENTIONEmbodiments of the invention provide an EMP device having an electro-discharge shorting mechanism. In its broadest sense, the invention covers EMP devices having a non-explosive material shorting mechanism. This type of shorting mechanism may enable generation of higher frequency electromagnetic pulses than is currently possible with traditional, explosive-containing shorting mechanisms.FIG. Whether external or as a core, the conductor can provide a ground return path for a spark gap, details which will be described below. One or more plasma discharge devices 106 are disposed at least partially along a length of conductive coil 102 and spaced apart from it.
Preferably, the plasma discharge devices 106 are spaced apart from conductive coil 102 approximately 5 mils (12.5?10?5 m).
The plasma discharge devices 106 create a traveling short circuit of the coil which compresses the magnetic field, and thus creates an electro-magnetic pulse.A spark gap 110 is positioned such that when activated by a current, the plasma discharge devices 106 create the electric discharge that triggers the electromagnetic pulse production, as will be explained further below. Devices or configurations of components other than spark gaps, or equivalents thereto, may be used to activate the plasma discharge devices 106 and are within the spirit and scope of the invention.Preferably all plasma discharge devices 106 are activated by the same spark gap. The other side of single spark gap 110 is connected to all plasma discharge devices 106 by conductive connectors, such as 108 and 114. Conductive connectors such as 108 connect the grounded end of spark gap 110 to each of the plasma discharge devices 106.
Conductive connectors such as 114 link a high voltage section of plasma discharge devices 106 to spark gap 110. Other configurations allowing for simultaneous current supply are also within the scope of the invention. 1 shows conductive connectors such as 114 converging in a substantially conical shape which is the preferred configuration. This shape may be advantageous as lengths of connectors such as 114 can be uniform, thus allowing simultaneous activation of the plasma discharge devices 106. An illustrative number of plasma discharge devices 106 is in the range of 1 to 20, with the preferred number being 12.One or more of plasma discharge switches 106 may be constructed as those shown in FIG. 2 depicts an illustrative embodiment of a plasma discharge device 200 shown in the form of two parallel plate capacitors. Plasma discharge device 200 has a first outer electrically conductive plate 202 and a second outer electrically plate 204.
A first electrically insulating plate 210 is adjacent to first outer plate inside face 206, and a second electrically insulating plate 212 is adjacent to second outer plate inside face 208.
An inner electrically conductive plate 214 is disposed between first electrically insulating plate 210 and second electrically insulating plate 212. First outer electrically conductive plate 202 is electrically connected to second outer electrically conductive plate 204 by a plate-connecting component 216, such as a conductive coil.Plasma discharge device 200 may be utilized in the present invention by applying a voltage to outer electrically conductive plate 204 while grounding inner plate 214 to create a potential difference therebetween.
Because the first and second outer electrically conductive plates 202 and 204 are initially charged to the same potential, no potential difference exists between them.
As noted above, a spark gap can be used to initiate a discharge of the plasma discharge device along its length. A current is initiated across the spark gap when a threshold voltage is applied to the plasma discharge device. When plasma discharge device 200 is activated, the outer conductive plate 204 is at a higher voltage relative to outer conductive plate 202.
An electric-discharge is thus created along edge 218 that travels at nearly the speed of light. This discharge creates a plasma between plasma discharge device 200 and the coil of the EMP device thereby short-circuiting the coil.
3 depicts a circuit diagram that illustrates parallel plate capacitors forming a plurality of plasma discharge devices 310. Further illustrated is a conductive coil 312 having a voltage applied thereto to create a magnetic field.The configuration of plates depicted in FIG.
Discharge of one of the outer plates of a pair of parallel plate capacitors within a plasma discharge device, such as plate 304 with plate 308, results in an arc between two outer plates, such as plates 302 and 304. This is analogous to an electric-discharge traveling along edge 218 of the plasma discharge device 200. The arc shorts conductive coil windings 312 to ground, creating a flux compression, and hence producing an electromagnetic pulse.
A potential applied to the coil to create a magnetic field is preferably in the range of about 1–3 KV.
