Electromagnetic Pulse (EMP) is an intense energy field that can instantly overload or disrupt numerous electrical circuits at a distance. Modern high technology microcircuits are especially sensitive to power surges, and the possible vulnerability of U.S. civilian computer systems to the effects of EMP has been discussed in the media. EMP can be produced on a large scale using a single nuclear explosion, and on a smaller, non-nuclear scale using a device with batteries or chemical explosives. Several nations, including reported sponsors of terr ....etc

In the 1980s, people feared neutron bombs that could kill everyone but leave buildings, roads, and cars intact. Today, we should fear a different kind of nuclear threat that can instantaneously destroy power grids, electronic systems, and communications along an entire coast but spare people.

The Electro Magnetic Pulse (EMP) effect was first observed during the early testing of high altitude airburst nuclear weapons. The effect is characterized by the production of a very short (hundreds of nanoseconds) but intense electromagnetic pulse, whi ....etc

I. Introduction
Current U.S. military transformation strategy centers on information dominance, network-centric warfare, and expeditionary operations. Operations Desert Storm and Iraqi Freedom demonstrated a spectacular evolution of capability in these key areas. Certainly, adversaries learned from Saddam s poor decision to face American forces head-on and will increasingly employ asymmetric attacks to defeat U.S. forces in the future. Electromagnetic pulse (EMP) weapons represent one of the most likely and potentially devastating opportuni ....etc
