Scientific definitions for Faraday cage
A container made of a conductor, such as wire mesh or metal plates, shielding what it encloses from external electric fields. Since the conductor is an equipotential, there are no potential differences inside the container. The metal hull of an aircraft acts as a faraday cage, protecting its occupants from lightning. Faraday cages are used to protect electronic equipment from such electrical interference as electromagnetic interference. Also called Faraday shield
