ABSTRACT:
A method for producing a durable electromagnetic and radio frequency interference shield between two or more structural members of a wall or enclosure and a shielded shelter produced using the method. In one embodiment, joints between structural members are preferably filled with an electrically conductive filler. A base coat of a metal spray that adheres well to the filler and structural member is then applied. At least one layer of a metal spray with magnetic field attenuation properties such as steel, and at least one layer of a metal spray that has plane wave attenuation properties such as tin are applied to the base coat. Optionally, a coat of protective or conductive paint is then applied to the top surface of the metal spray layers. An enclosure with shielded joints according to the present invention has superior shielding capability and durability over the art.
