Abstract: An electromagnetic shielding and/or containing heatsink with venting capabilities, comprising a heatsink block, an aperture, and a thermal coupler, is disclosed. The heatsink comprises a thermally conductive material. The aperture is coupled to the heatsink block and allows a thermal carrier to pass from a first side of the heatsink block to a second side of the heatsink block. The aperture is sized to prevent at least a first electromagnetic frequency lower than a cutoff frequency from passing through the aperture. The thermal coupler is coupled to the heatsink block and couples the heatsink block to a heat source.

Abstract: An apparatus and method for electromagnetic shielding is disclosed. The apparatus comprises an enclosure, a plate, and a material disposed between the enclosure and the plate. The enclosure has an aperture that is substantially transmissive to electromagnetic radiation. The plate is coupled to the enclosure proximate to the aperture, and covers the aperture completely with an area of overlap on all sides of the aperture. The material is disposed between the plate and the enclosure in the area of overlap between the plate and the enclosure and provides intimate contact between the enclosure and the plate to substantially prevent electromagnetic radiation from passing through the aperture when the plate is coupled to the enclosure.
