Abstract: A passive Electromagnetic Interference (EMI) dissipation apparatus typically utilized with an active host component to reduce self-generated and externally-generated electromagnetic interference and to improve the performance of the host component is disclosed. The apparatus includes a housing and a circuit located within the housing. The circuit includes a plurality of pyramidal-shaped resonating chambers having internally conductive surfaces covered with a layer of electrically resistive material, a plurality of quartz resonators each mounted upon a damping compound, and a plurality of permanent magnets each including a magnetically permeable bar. The electromagnetic interference is dissipated in the circuit over a broad range of frequencies in the form of heat. In a preferred embodiment, the plurality of permanent magnets and the corresponding plurality of permeable bars are mounted within a common chamber located immediately below the base of each of the pyramidal-shaped resonating chambers.
