A microwave has that mesh on it, because it's the same frequency as the microwaves. By placing that mesh on the front, it stops the microwaves transmitting through the front window bit. Not sure what it's called, in physics, but that's what it does. Not sure whether it's a faraday cage though.

In theory, it should work as one, but I wouldn't swear by it....just because I've not tested it. The same is true with the mobile phone checker. A mobile phone can't transmit through a thatched roof building. It's not because of the thatch, but it's because of the metal chicken wire covering the roof. A thatched home isn't a faraday cage, and the emp will draw through the walls, however you can't make a phone call through it.

The safest version I know of, a metal bird cage, with a big grounding wire. I've heard of those being tested, and coming up trumps. Again, not my own experiments, but from people I've spoken to who say they have tested the system.
