Faraday Cage

From TinWiki.org

In a way it could be considered the ultimate tin foil hat.

Named after Michael Faraday a Faraday Cage is an enclosed environment that does not allow the transfer of electromagnetic energy from the inside or for this energy to cross the barrier from the outside.

It serves as a shield against intrusion from external eavesdropping by preventing any signal leak via a computer screen or other electronic equipment. It also serves to prevent most transmitting bugging devices to not function from inside the protected area.

A Faraday Cage can be of any size up to the scale of an entire building. Some corporate and government buildings use this protection to ensure security, and some members of the conspiracy community have taken great measures to install them in their own homes.

Everyone Has One

Some simple examples of the home use we make of this science would be a kitchen microwave oven and even the family car. The microwave oven has a cage to prevent the escape of energy that would harm the human body. Any vehicle with a metal frame and body will transfer even the energy of a lightening strike without harming the occupants.

Most computer parts are shipped in antistatic bags that are themselves a Faraday Cage.


Glass Protection

Protective coatings can be applied to glass that slightly tints the windows but has a fine metallic mesh embedded in the polymer. The mesh prevents the transfer of electromagnetic energy.


Deflective Paint

Several companies market special paints that can be applied to walls. These paints have fine metallic particles that bond together to form an electromagnetic barrier.
