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.

A challenge arose in the form of a powerful AM radio antenna from a sports station broadcasting 50,000 watts of power a few miles away. To prevent Van Halen picking up boxing fights and football games through his guitar wireless units, engineers wrapped a layer of grounded chicken-wire fencing around the studio, turning it into a Faraday cage.
Its construction began in March 1934 during Nazi rule as a Reichsautobahn, the section between Karlsruhe and Salzburg having been completed by the time road works were discontinued in World War II. Although most parts have been modernized and extended since, significant sections remain in their original configuration from the 1930s - 2+2 lanes ...
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]
The fundamental principle used in Franklin-type lightning protections systems is to provide a sufficiently low impedance path for the lightning to travel through to reach ground without damaging the building. [9] This is accomplished by surrounding the building in a kind of Faraday cage. A system of lightning protection conductors and lightning ...
The calculated data allows using C 60 fullerene as a Faraday cage, [13] which isolates the encapsulated atom from the external electric field. The mentioned relations should be typical for the more complicated endohedral structures (e.g., C 60 @C 240 [ 14 ] and giant fullerene-containing "onions" [ 15 ] ).
