Hi, I am having a little microwave experiment, and I want to shield some
cracks from leaking microwaves. A pal said to me that a paper-type
called "mica" is used for such reasons in microwave ovens. Actually what
he told me is that it allows microwaves to pass through, but it blurs
them so as they are not focused as before.

Is it true, or does anyone know any better way to make leaking
microwaves less harmful (apart from Faraday cage, this is too hard for
me to make, I suppose).

And he had a straight face when he told you that?


Is it true,

Only in your friend's make belive world.

You suppose? I don't. A Farady cage is the answer, basically.

OH, and mica is not a type of paper, either.

On the web I came across references to Velostat. Does anyone know if it
absorbs microwaves and where may one get it from?
