An e-bomb (electromagnetic bomb) is a weapon that uses an intense electromagnetic field to create a brief pulse of energy that affects electronic circuitry without harming humans or buildings. At low levels, the pulse temporarily disables electronics systems; mid-range levels corrupt computer data.The effect is characterized by the production of a very short (hundreds of nanoseconds) but intense electromagnetic pulse, which propagates away from its source with ever diminishing intensity, governed by the theory of electromagnetism. The ElectroMagnetic Pulse is in effect an electromagnetic shock wave.
Key technologies which are extant in the area are
1.Explosively pumped Flux Compression Generators (FCG)
2.explosive or propellant driven Magneto-Hydrodynamic (MHD) generators
3.Virtual Cathode Oscillator or Vircator
