Composite materials for shielding electromagnetic radiation that combine high shielding effectiveness over a broad frequency range with light weight, ease of processing, and low cost compared to metal sheaths. The composites contain conductive fillers like carbon black or metal fibers dispersed in a polymer matrix. The filler content can be lower than in metal-only shielding due to the composite's combined absorption and reflection properties. The filler size and distribution affect shielding effectiveness by controlling reflection, absorption, and permeability. The composite structure provides multiple internal reflections and scattering to increase absorption path length. This enables shielding of GHz frequencies where simple metal sheaths have limitations.
