ELECTROMAGNETIC INTERFACE SHIELD

Abstract:

The present invention relates to an enclosure and method of manufacture of an enclosure arranged to define a cavity for electromagnetic shielding of equipment to be housed within the cavity, the enclosure comprising: an aperture (16) arranged to allow access to the enclosure; a conductive membrane (18) arranged to close the aperture; and a waveguide element (20) arranged between the conductive membrane (18) and the cavity; wherein the waveguide element (20) and conductive membrane (18) are configured to attenuate electromagnetic radiation originating from the equipment to be housed within the enclosure (10) thereby to inhibit the transmission of electromagnetic radiation from the enclosure via the aperture (16).
