First, the EMP that would likely be generated from nuclear or E-bombs would probably pass through the protection normal consumers have against other electromagnetic interference and power surges (EMI). Thus, such contraptions wouldn't offer much help.
That said, the good news is that the military is probably far more ready to take on EMP than normal consumers. As Daryl Gerke and William Kimmel, principals at Kimmel Gerke Associates, an EMC consulting and training firm said in Interference Technology Magazine:
"Military equipment may be subjected to very high levels of RF energy (radar and radio transmitters), lightning and nuclear EMP effects. MIL-STD-461E, the key military EMC specification, addresses these multiple environments through a matrix of recommended requirements. For example, an electronic device used in a submarine will have different requirements than a device used in a helicopter."
So that's good to hear. But what about us and society at large?
What can your everyday civilian do to protect themselves against the possibility of an EMT attack?
1. Have a lot of battery operated devices on hand and the batteries to use them. Further, these appliances should have cords and antennas 30 inches or less in length. The reason for this is simple: Metal pulls in EMP and makes it more dangerous. Thus, less metal is good. Further, keep these appliances away from metal.
2. Stay 8 feet from large scale metal fixtures yourself. In fact, when EMP is concentrated by metal it can actually be dangerous to man in and of itself.
3. Harden your equipment (another way of saying, protect it from EMP). Some considerations include the use of tree formation circuits (not standard loop formations), induction shielding around components, self-contained battery packs, loop antennas, and Zener diodes. In addition, grounding wires for each separate instrument into a system could help as well.
4. A new device called the Ovonic Threshold Device (Energy Conversion Devices of Troy, MI) is a solid state switch that opens a path to ground when a massive surge of EMP is encountered by a circuit. This would help in a big way.
5. Use a Faraday Box to store equipment in. Makeshift Faraday boxes can be made from metal filing cabinets, ammunition containers, and cake boxes. That said, the device you are protecting must not touch the metal container (use insulation: paper, cardboard, whatever). Further, there can be no holes. Last, if the box seems less than adequate, you may wrap it in aluminum foil for more protection.
6. Wrap your rooms in aluminum foil. Well, it's certainly extreme, but thought it worth mentioning. After you do so, cover it with some type of fake wood, etc.
7. Cars are already a metal box. Thus, most of them would survive. That said, gas would be a problem. So have a lot of that and food on hand (remember that refrigerators and water sanitizing devices would go out).
In the end, we don't know when or how disaster may strike. What we do know is that we need to be ready. And since an EMP attack is a stated possibility that could wreak tremendous havoc. . .
We need to be ready for that as well.
