Your microwave does this. It's a Faraday cage.

 

Put your cell phone in there, close the door (don't turn on the microwave silly) and watch as your cell service go's to nothing.

 

Your microWAVE is designed to keep the frequency waves in….and it also keeps signals out.

 

Protip, if you want to discuss sensitive info, have everyone put their cells phones in the microwave first.
