How to shield your electronics.

Hello Peace. I'm glad you are interested. Here some clarification.

Yes, multiple foil will work. The important is having a good electric conductor, aluminum is one, like silver, copper, iron, steal.

Don't bother about car engine, it's an explosion (gasoline) motor and it won't be affected. The batteries will take it. Their capacity and power (Amp/hour) will support it. But the electronics of your car, sensors, processors, memories, etc... might not like it. Recent cars, 2000+ years, have many of them from electronic starters to flow fuel control. But I wouldn't worry about it because the frame and structure of your car will act as an "metal shielding" and will reflect most of the wave.

Yes, CB antenna will do.

What is mostly susceptible to EMP is electronic component, which work on Direct Current low Voltage, 5 VDC to 24 VDC, and haven't a high capacity to support high frequencies and high magnitude. Any devices working on 120 Alternative (50/60Hz) Current Voltage, 120 VAC and higher, will absorb the impact even more if it isn't running and unplugged.

The noise is an electromagnetic wave of high frequencies, device running under alternative voltage/current are made to work with frequencies, up to a certain limit in frequencies/amplitude. But electronic component, like processors, memories, etc... are not made to deal with high frequencies and especially if the signal (noise) is strong. They can heat and burn from inside.

Only these need to be shielded in my humble opinion.

I hope it clarifies it.

Namaste, Steven
