2. INTRODUCTION - CBS News, 3-25-03 - Time Magazine, 1-19-03
"The U.S. Air Force has hit Iraqi TV with an experimental electromagnetic pulse device called the 'E-Bomb' in an attempt to knock it off the air and shut down Saddam Hussein's propaganda machine. Iraqi satellite TV, which broadcasts 24 hours a day outside Iraq, went off the air around 4:30 a.m. local time."
- CBS News,
       E-bombs can unleash in a flash as much electrical power—2 billion watts or more—as the Hoover Dam generates in 24 hours. [And], although the Pentagon prefers not to use experimental weapons on the battlefield, "the world intervenes from time to time," - Defense Secretary Donald Rumsfeld.

3. WHAT IS E-BOMB? (ELECTROMAGNETIC BOMB)
IT IS THE WEAPON OF ELECTRICAL MASS DISRUPTION.
IT CAN DESTROY POWER GRIDS,
ELECTRONIC SYSTEMS and COMMUNICATIONS ALONG AN ENTIRECOAST BUT SPARE PEOPLE.

4. BASIC IDEA
AN ELECTROMAGNETIC PULSE WEAPON EMP IS DESIGNED TO OVERWHELM THE ELECTRIC CIRCUITRY WITH AN INTENSE ELECTRO MAGNETIC FIELD
ELECTRIC CURRENT GENERATES MAGNETIC FIELD AND CHANGING MAGNETIC FIELD IN TURN GENERATES A CURRENT
AN INTENSE FLUCTUATING MAGNETIC FIELD CAN PRODUCE A LARGE AMOUNT OF CURRENT WHICH CAN BURN LOW POWER SEMI CONDUCTOR DEVICES

5. DESIGNING A E-BOMB:
BASICALLY THERE ARE TWO METHODS FOR DESIGNING A E-BOMB
1.FLUX COMPRESSION GENERATOR (FCG) METHOD
2. VIRTUAL CATHODE OSCILLATOR (VIRCATOR)
METHOD

6. FCG METHOD FCG IS A DEVICE WHICH CAN PRODUCE PEAK OF ELECTRICAL
ENERGIES OF MEGA JOULS IN TENS TO HUNDREDS OF MICRO
SECONDS OF TIME.
IT CONSISTS OF :-
1) POWER SUPPLY
2) EXPLOSIVE PUMPED COPPER CYLINDER SURMOUNTED BY
HELICAL COILS.
3) A MICRO WAVE SOURCE

9. VIRCATOR METHOD THE OPERATING PRINCIPLE OF VIRCATOR IS MORE COMPLEX
THE PRINCIPLE OF THE VIRCATOR IS THAT OF ACCELERATING A HIGH
CURRENT ELECTRON BEAM AGAINST A MESH (or foil) ANODE.MANY
ELECTRONS WILL PASS THROUGH THE ANODE, FORMING A BUBBLE OF
SPACE CHANRGE BEHIND THE ANODE. THIS SPACE CHARGE REGION
WILL OSCILLATE AT MICROWAVE FREQUENCIES. IF THE SPACE CHARGE
REGION IS PLACED IN TO RESONANT CAVITY WHICH IS APPROPRIATLY
TUNED,VERY HIGH PEAK POWERS MAY BE ACHIEVED.
THE OPERATING PRINCIPLE OF VIRCATOR IS MORE COMPLEX
than THAT OF FCG METHOD.

12. DELIVERING THE BOMB BOMB CAN BE DELIVERED THROUGH :- 1.CRUISE MISSILE
2.CONVENTIONAL AIRCRAFT
3. AIR TO AIR MISSILE

13. E-BOMB’S EFFECT vehicle control systems bombs
IT WOULD TEMPORARILY JAM ELECTRONICS SYSTEMS ,MORE
INTENSE PULSES WOULD CORRUPT IMPORTANT COMPUTER
DATA AND VERY POWERFUL BURSTS WOULD COMPLETELY FRY
ELECTRICAL AND ELECTRONIC EQUIPMENTS.
AN E-BOMB COULD EFFECTIVELY NEUTRALIZE:-
vehicle control systems
targeting systems, on the ground and on missiles and
bombs
communications systems
navigation systems
long and short-range sensor systems

14. DEFENCE AGAINST E-BOMB
The most effective defence against electromagnetic bombs is to prevent their delivery by destroying the launch platform or delivery vehicle
The most effective method is to wholly contain the equipment in an electrically conductive enclosure, termed a Faraday cage, which prevents the electromagnetic field from gaining access to the protected equipment
systems which can be expected to suffer exposure to the electromagnetic weapons effects must be electromagnetically hardened

15. LIMITATIONS
The limitations of electromagnetic weapons are determined by weapon implementation and means of delivery. Weapon implementation will determine the electromagnetic field strength achievable at a given radius, and its spectral distribution. Means of delivery will constrain the accuracy with which the weapon can be positioned in relation to the intended target. Both constrain lethality.

16. CONCLUSION
Electromagnetic bombs are Weapons of Electrical Mass Destruction with
applications across a broad spectrum of targets, spanning both the
Strategic and tactical. Because E-bombs can cause hard electrical kills
Over larger areas than conventional explosive weapons of similar mass,
They offer substantial economies in force size for a given level inflicted
damage.
E-bombs can be an affordable force multiplier for military forces which are
under post Cold War pressures to reduce force sizes, increasing both their
combat potential and political utility in resolving disputes.
it is incumbent upon such military forces to appreciate both the offensive
and defensive implications of this technology. It is also incumbent upon
governments and private industry to consider the implications of the
proliferation of this technology, and take measures to safeguard their vital
assets from possible future attack
