The effects of EMP on conductors can be mitigated by utilizing zener diodes, MOVs (Metal Oxide Varistors), THYZORBs and the like. There are many commercially available devices that can be utilized.

The long wavelengths (10 kHz-100 MHz) created by EMPs and HEMPs do not require shielding to be airtight to be effective. Nor do the shielding materials need to be thick & heavy; aluminum foil can be effectively used as a shielding material. Large gaps (such as doors or windows) will have to be dealt with in some manner.

Proximity means everything; the closer you are to the EMP "source", the less effective your "hardening" measures will be.

I'm not saying an attack as described in Joanie's post would be a walk in the park; EMP generators will no doubt be only the opening salvo, followed by many ground strikes. If we're going to be 'realistic', the nukes making it to the ground will be of far greater concern than the EMP generators. If you live in a major metropolitan area, you're probably hosed. Personally, I would rather be within 100 feet of ground zero than to be one of the 'survivors' . . .
