ABSTRACT:
An electromagnetic shielding assembly comprises a substrate, an electrically conductive carbon composition shielding plate, and a metallic plate, wherein the electrically conductive carbon composition plate is physically and electrically coupled to the substrate and the metallic plate. By positioning the substrate such that a circuit that emits, or is sensitive to, electromagnetic energy is substantially enclosed within a cutout area of the electrically conductive carbon composition plate, the electromagnetic shielding assembly substantially contains the electromagnetic energy radiating from, or towards, the circuit.
