A Faraday cage or Faraday shield is an enclosure used to block some electromagnetic fields. A Faraday shield may be formed by a continuous covering of conductive material, or in the case of a Faraday cage, by a mesh of such materials. Faraday cages are named after scientist Michael Faraday, who first constructed one in 1836. [1]
A conductive enclosure used to block electrostatic fields is also known as a Faraday cage. The amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of holes in a shield to an incident electromagnetic field.
An electromagnetic pulse (EMP), sometimes called a transient disturbance, is a short-duration pulse of energy. This energy is usually broadband by nature, although it often excites a relatively narrow-band damped sine wave response in the victim. Pulse signals divide broadly into isolated and repetitive events.
Four-conductor shielded cable with metal foil shield and drain wire. Coaxial cable. Electronic symbol for a shielded wire. A shielded cable or screened cable is an electrical cable that has a common conductive layer around its conductors for electromagnetic shielding. [1]
A Faraday cage does not offer protection from the effects of EMP unless the mesh is designed to have holes no bigger than the smallest wavelength emitted from a nuclear explosion. Large nuclear weapons detonated at high altitudes also cause geomagnetically induced current in very long electrical conductors.
A Faraday Shield is a plate of conductive metal connected to ground. It blocks Electrostatic fields, and also prevents Electric fields passing through it. Example: an Electrostatic shield embedded in a Transformer. A Faraday Cage is a completely enclosed box with welded or bolted seams. Example: the classic "Screened room" used in EMC testing.
