. INTRODUCTION
An e-bomb, or e-bomb, is a weapon designed to take advantage of this dependency. But instead of simply cutting off power in an area, an e-bomb would actually destroy most machines that use electricity. Generators would be useless, cars wouldn't run, and there would be no chance of making a phone call. In a matter of seconds, a big enough e-bomb could thrust an entire city back 200 years or cripple a military unit.
At low level, the pulse temporarily disable electronic systems; mid-range level corrupt computer data.
At high level completely destroy electronic ckts. Thus disabling any type of machine that uses electricity, including computer, radios, and any ignition systems in vehicles. Although not directly lethal, an e-bomb would devastate any target that relies upon electricity: a category encompassing any potential military target and most civilian area of world as well.
The effect is usually not noticeable beyond 10 km of the blast radius unless the device is nuclear or specification designed to produce an electromagnetic pulse. Small nuclear weapons detonated at high altitude can produce a strong enough signal to disrupt or damage electronics many miles from the locus of the explosion. During a nuclear EMP, HE magnetic flux lines of the earth alter the dispersion of energy so thtat it radiates very little to the north, but spreads out East, West, and South of the blast. The signal is divided into several time components, and can result in thousands of volts per meter of electromagnetic energy.
The Basic Idea:
The basic idea of an e-bomb or more broadly, an electron magnetic pulse (EMP) weapon is pretty simple. These sorts of weapons are designed to overwhelm electrical circuitry with an intense electromagnetic field.
If we read how radio works, then we know an electromagnetic field in itself is nothing special. The radio signals that transmit AM, FM, television and cell phone calls are all electromagnetic energy, as is ordinary light, microwaves and x-rays.
For our purpose, the most important thingh to understand about electromagnetism is that electric current generates magnetic fields can induce electric current. This page form how radio work explain that a simple radio transmitter generates a magnetic field, in turn, can induce an electrical current in another conductor, such as a radio receiver antenna. If the fluctuating electrical signal represents particular information, the receiver can decode it.
THE TECHNOLOGY BASE FOR CONVENTIONAL ELECTROMAGNETIC BOMBS
The technology base which may be applied to the design of electromagnetic bombs is both diverse, and in many areas quite mature. Key technologies which are extant in the area are explosively pumped Flux Compression Generators (FCG), explosive or propellant driven Magneto-Hydrodynamic (MHD) generators and a range of HPM devices, the foremost of which is the Virtual Cathode Oscillator or Vircator. A wide range of experimental designs have been tested in these technology areas, and a considerable volume of work has been published in unclassified literature.
EXPLOSIVELY PUMPED FLUX COMPRESSION GENERATORS
The explosively pumped FCG is the most mature technology applicable to bomb designs. The FCG was first demonstrated by Clarence Fowler at Los Alamos National Laboratories (LANL) in the fifties.
The FCG is a device capable of producing electrical energies of tens of Mega Joules in tens to hundreds of microseconds of time, in a relatively compact package. With peak power levels of the order of Terawatts to tens of Terawatts, FCGs may be used directly, or as one shot pulse power supplies for microwave tubes. To place this in perspective, the current produced by a large FCG is between ten to a thousand times greater than that produced by a typical lightning stroke.
The central idea behind the construction of FCGs is that of using a fast explosive to rapidly compress a magnetic field, transferring much energy from the explosive into the magnetic field.
The initial magnetic field in the FCG prior to explosive initiation is produced by a start current. The start current is supplied by an external source, such a high voltage capacitor bank (Marx bank), a smaller FCG or an MHD device. In principle, any device capable of producing a pulse of electrical current of the order of tens of Kilo Amperes to Mega Amperes will be suitable.
The nucler EMP Threat:-
Researchers concluded that the electrical disturbance was due to the Compton effect, theorized by physicist Arthur Compton in 1925. Compton's assertion was that photons of electromagnetic energy could knock loose electrons from atoms with low atomic numbers. In the 1958 test, researchers concluded, the photons from the blast's intense gamma radiation knocked a large number of electrons free from oxygen and nitrogen atoms in the atmosphere. This flood of electrons interacted with the Earth's magnetic field to create a fluctuating electric current, which induced a powerful magnetic field. The resulting electromagnetic pulse induced intense electrical currents in conductive materials over a wide area.
