Protection against EMP ...
Let's say that I want to protect some important electronics devices against EMP.
Let's say that they need to work 24/7 and that they are, thus, connected to an external source of power (electrical socket before EMP, and solar panel after EMP).
Let's say that they need to emit and receive RF signals.
1) As there are electrical connections with the exterior, a Faraday cage would be pointless, wouldn't it ?
2) Would a solar panel survive to an EMP ?
3) Is this possible to use the Faraday cage as an antenna for RF communication ? (I guess it's a stupid question as connecting the cage to the device would make the cage part of the device ...)
4) Are thin and transparent gold foils enough to act as a Faraday cage ?

Edit2 : an article about EMP protection.
The first part is about EMP from nuclear bombs. The last part gives some clue about HMP.
