Abstract
A shielding enclosure for preventing propagation of electromagnetic radiation into or out of the enclosure comprising a support structure and a plurality of sheets of electrically conductive material supported thereon. Each of the sheets has an edge extending therearound and a region of overlap extending inwardly of and along the edge. The region is in overlapping engagement with the region of overlap of sheets adjacent thereto on the support structure so as to define a wave guide gap. Adjacent sheets are pressed together by pressure plates at the overlapping regions to maintain a gap width through which the electromagnetic radiation cannot propagate. Shielding components used to construct a shielding enclosure are also disclosed.
