Electro Magnetic Pulse (EMP) Hardening• Why EMP Protection?– Manmade (EMP Bombs), Natural (Solar Flares)– 50,000 volts / meter field strength– Can permanently disable civil/military installations– Command, Control & Communication failure• How to protect against EMP?– Double Skinned Sandwich Enclosures (Faraday cage)– EMP Filters, Wave guide feed-through– Improved Shielding, Reinforced paths to GND to steer pulse away from equipment.– Honeycomb air vents– EMP Hardened Circuits and Equipment– Migration to Fiber Optic media• Trade off– Increase in Equipment Weight– Higher Equipment costs– Higher installation and maintenance CostsSTRATEGIC ELECTRONICS DIVISION9
