Faraday cage

The Faraday cage, named after the English physicist Michael Faraday, is a cavity surrounded by an electrically conductive material.

Such condu

ctiveshielding prevents electric fields

fromentering the cavity and functionally impairing the electronic components or assemblies contained therein. A metal box, enclosure, rack, or room that is RF-tightly surrounded by a metallic shield constitutes a Faraday cage. Faraday cages are often constructed of Mu metal because this metal has a particularly high permeability

.Electric fields incident on a faraday cage are conducted around the hollow body in the shielding and do not enter

it.Inside the Faraday cage, there are no electric fields penetrating from the outside.

In practice, lightning protection systems and other technical equipment against lightning protection, as well as rooms for interference radiation measurements or equipment shielding are designed as Faraday cages.
