Faraday cage
Electromagnetic field shield
A Faraday cage is an enclosure of conductive material that blocks electromagnetic fields.
Radio waves, microwaves, and static electricity cannot pass through the mesh or solid metal shell.
The principle works both ways—signals can't get in or out.
Named for physicist Michael Faraday.
Microwave ovens contain one to keep radiation inside; some buildings function as unintentional Faraday cages, blocking cell reception.
