3. Electronic Warfare
“…is the use of the electromagnetic spectrum to deny its use by an adversary.” -wikipedia.org
Employs technology to interfere or jam an adversary’s communications system

4. Electromagnetic Bombs, or E-Bombs

5. Electromagnetic Bombs, or E-Bombs
A form of electronic warfare

6. Electromagnetic Bombs, or E-Bombs
A form of electronic warfare
Employs electromagnetic force, one of the four fundamental forces

7. The Vircator
Virtual Cathode Oscillator

8. The Vircator Virtual Cathode Oscillator
Most popular of the various HPM, or high-powered microwave, devices

9. The Vircator Virtual Cathode Oscillator

Vacuum tube

10. The Vircator Deployed in a Bomb
Wide “lethal” range

11. The Vircator Deployed in a Bomb
Wide “lethal” range
Its electromagnetic pulse can be generated without the need for a nuclear explosion

12. The Vircator Deployed in a Bomb
Has the ability to render useless any electronic equipment exposed to its pulse

13. Defending Against The Vircator And Other HPM Devices
The Faraday cage

14. Defending Against The Vircator And Other HPM Devices
The Faraday cage
Prevents the electromagnetic field from gaining access to protected equipment

15. Vulnerability of The Faraday Cage
Protected equipment must be linked with the outside world: data and power

16. Vulnerability of The Faraday Cage
Protected equipment must be linked with the outside world: data and power
Data: fiber optics; power: ongoing problem
