Michael Faraday (1791-1867)

The Faraday Cage Effect (named after its discoverer) means that the
electric charge on a conductor sits on the outer surface of it.
Therefore, no electrostatic field is present within the conductor.

If the radio pulse is large enough it can pass through a thin tin foil.
