Abstract
A shielded access apparatus for enabling personnel access to an enclosure which is shielded to prevent propagation of electromagnetic energy into and out of the enclosure. The apparatus includes an access enclosure of electrically conductive material and first and second openings in the enclosure. A shield is positioned in the enclosure between the first and second openings for preventing radiated electromagnetic energy passing through one of the openings from travelling along a straight line to the other opening. Absorption material lines the interior of the enclosure and absorbs radiated electromagnetic energy passing through the enclosure.
