To a large degree, Faraday cages also shield the interior from external electromagnetic radiation if the conductor is thick enough and any holes are significantly smaller than the radiation's wavelength. For example, certain test procedures of electronic components or systems that require an environment devoid of electromagnetic interference may be conducted within a so-called screen room. These screen rooms are essentially labs or work areas that are completely enclosed by one or more layers of fine metal mesh or perforated sheet metal. The metal layers are connected to earth ground to dissipate any electric currents generated from the external electromagnetic fields, and thus block a large amount of the electromagnetic interference. This application of Faraday cages is explained under electromagnetic shielding. | To a large degree, Faraday cages also shield the interior from external electromagnetic radiation if the conductor is thick enough and any holes are significantly smaller than the radiation's wavelength.

The | The {{Class|Point Blank|prowler}} ''[[UNSC Point of No Return|Point of No Return]]'' is equipped with a secure, insulated room known informally as [[Odin's Eye]] or "the cage", which functions as a Faraday cage and is as such considered one of the most secure places in human territory.{{Ref/Novel|GoO|Chapter=2}} During the [[Onyx Conflict]], [[thermal blanket]]s were used to create a primitive Faraday cage around Dr. [[Catherine Halsey]] when she was working on a [[portable computer|laptop]], to avoid detection by the [[Onyx Sentinels]]' electromagnetic sensors.{{Ref/Novel|GoO|Chapter=21}} | ||
