E-BOMB A WEAPON OF ELECTRICAL MASS DESTRUCTION Presented by: ANKIT KUMAR EN-III YEAR

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, 3-25-03        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. - Time Magazine, 1-19-03

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.

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

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

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

FCG DIAGRAM

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.

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

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

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

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.

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
