Abstract
Shielding means for electromagnetic radiation, particularly that of radio frequency, comprises a enclosure fabricated from non-conductive material and having on at least one of the interior or exterior walls a layer of copper metal. The latter has been applied by coating the surface of the wall with a suspension of particles of cuprous oxide (or like non-conductive metal derivatives capable of being reduced to conductive free metal) in a curable resinous material, at least partially curing the coating, reducing to free metal the cuprous oxide or like particles in the surface of the coating and then electrolessly plating the coating with copper.
