  1. 1. SUBMITTED BY: DEEPAK MITTAL B.E. FINAL YEAR COLLEGE OF TECHNOLOGY & ENGINEERING,UDAIPUR
  2. 2. INTRODUCTION  Future warfare compaigns will require more suitable to achieve shock effect over large target sets with small Attacking force  Electromagnetic bombs (E-Bomb) can preform such a role  Developed by Dr. Carlo Kopp, Associate Fellow AIAA And Freelence Defense Analyst  It can destroy Power Grids,Electronics And Communication System along an entire cost but spare human and other Living species
  3. 3.  It is weapon of Electrical Mass Disruption  It is based on Electromagne- tic Pulse Theory  This weapon change magnetic field which couple with electric circuitry to produce damage currents surges
  4. 4. 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 BASIC IDEA
  5. 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)
  6. 6.  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 Colis 3) A Micro Wave Source FCG METHOD
  7. 7. Events series when the bomb goes off:  Capacitors connects to Stator  sets electrical current through wires  Generates Intense Magnetic Field.  Fuze mechanism ignites the explosive material  Explosion travels as wave through the middle of the armature cylinder OPERATION OF E-BOMB
  8. 8. Continued…  Explosion passes through cylinder  Cylinder comes in contact with stator winding  creates a short circuit  cuts the stator off from its power supply.  Moving short circuit compresses Magnetic Field  generates Intense Electromagnetic burst.
  9. 9.  The principle of VIRACTOR is that of acceleraing a high current electron beam against a mesh(or foil) anode  Many electron will pass through the anode forming a bubble of space charge behind the anode  This space charge region will oscillate at microwave frequencies. If the space charge region is placed into resonant cavity which is appropriately tuned,very high peak powers may be achived.  The operating principle of VIRACTOR is more complex than that of FCG METHOD VIRACTOR METHOD
  10. 10.  Armature - copper tube / fast explosive  Stator - helical heavy wire coil  Initiator - plane wave explosive lense  Jacket - prevents disintegration due magnetic forces
  11. 11. BOMB CAN BE DELIVERED THROUGH :- 1.CRUISE MISSILE 2.CONVENTIONAL AIRCRAFT 3. AIR TO AIR MISSILE Delivery of E-bombs
  12. 12. TARGETING E-BOMB  fixed installations (buildings, radar and comms sites ) - conventional methods  radiating mobile / hidden targets (ships, mobile SAMs) - use ESM or ELS  non radiating mobile / hidden targets - use Unintentional Emissions (UE)
  13. 13. IT WOULD TEMPORARILY JAM ELECTRONICS SYSTEMS ,MORE INTENSE PULSES WOULD CORRUPT IMPORTANT COMPUTER DATA AND VERY POWERFUL BURSTS WOULD COMPLETE 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. 14. DEFENCE AGAINST BOMB  convert computer rooms in to Faraday cages  use optical fibers for data  isolate power feeds with transient arrestors  use electromagnetic “air lock”  shielding must be comprehensive
  15. 15.  Means of implementing E-Bombs are difficult.  Means of delivery constrain the accuracy of weapon.  Atmospheric propagation of waves.  Difficult kill assessment LIMITATATION
  16. 16.  Offers a very high payoff in attacking the fundamental information processing and communication facilities  E-bombs can cause hard electrical kills over larger areas than conventional explosives  Measures should be taken to safeguard against future attacks
