What is a Faraday Shield?
Sometimes referred to as a Faraday cage, the Faraday shield is a metallic device that is designed to block and focus electric fields. Often constructed as a sheet of metal, the Faraday shield is used in several different types of applications, ranging from telecommunications to medical equipment. The concept of the Faraday shield was first developed by Michael Faraday, a physicist with a special interest in the control of electricity fields. Beginning in 1836, Faraday built and explained the function of Faraday shields. The earliest of these Faraday cages or shields were in the form of a metal enclosure, often using a metal mesh to create an enclosed space for the transmission of current or waves. Faraday saw the shield as a way of preventing various electromagnetic waves from bisecting and interfering with one another. The Faraday shield would make it possible to operate multiple pieces of machinery within close proximity to one another, with no electrical interference occurring. In m
