What about them?

I'm sure there is, but I don't know it. Notice how that ignorance 
doesn't prevent me from using a microwave :)

Because a metal mesh won't make the microwave explode.

I already explained this. It's an antena. Electromagnetic radiation is 
an alternating magnetic field, hence it induces an alternating current 
on metal (technically, it induces a current on anything, but metal works 
best because the electrons are poorly associated with their parent atoms 
- this is the same reason why metals are good conductors of 
electricity). An antena is designed to maximize this effect (the induced 
current), so that the current can be detectable and then translated into 
video or sound.

Maybe Jean didn't mean "nothing" that literally.

Cheers,
Daniel.
