/diy/ - Do It Yourself

You say this with such certainty. It sounds like you don't even know how it works.

When a conductive material is exposed to an external electric field, the electrons inside of it will arrange themselves in a way that creates an opposing field that directly cancels out the external one at every point inside of the conductor. Being completely surrounded by a conductor is like being inside a large conductor, so the same effect applies.

It certainly does not have to be copper. Any metal is a good enough conductor to make it work well. Aluminum is almost as good a conductor as copper, and it is certainly more effective per unit cost. If cost is equalized, then you get a far thicker wall of aluminum than copper for the same price, so the aluminum would actually outperform. It does not have to be mesh either. Mesh is often used to save on material cost, since as long as the holes are much smaller than the wavelength of the incoming radiation, it will act like a solid barrier would. Basically, mesh and solid walls would have the same effect if you're looking to shield from RF and microwaves.

Same as above, but with less contempt because you weren't asserting that everyone else was wrong.

READ, PEOPLE, READ!
YOU'RE A FOOL IF YOU TRY TO HARNESS FORCES YOU DON'T UNDERSTAND.

I don't expect you'll feel any different, but why not, go ahead. Try your bed first, since that'll require much less material. If you do enjoy it, then you can move on to your room.
