Synthetic dielectric material for broadband-selective absorption and reflection

This invention relates to material for broadband-selected absorption and reflection of electromagnetic waves for all frequencies below optical (hereinafter referred to as RF) using dilute concentrations of metallic particles suspended in a lightweight dielectric for such applications as radar cross section suppressors, microwave heat exchangers, plasma generators, transformation of RF energy into thermal optical energy, shields for RF discharge devices, etc., and lightweight RF broadband reflecting material for such applications as radar reflectors, broadband antennas with prescribed or variable gain pattern, optically transparent RF shields, EMI shields and RF filters. Such absorptive material is useful in antenna-communication links (low elevation angles), RF microwave laboratory insulation, EMI absorptive shields. Such reflective material is useful for satellite antennas, communication links, cable television, shielding electronic computers, computer games, microwave ovens commercial RF microwave laboratory shielding and in high RF energy discharge technology in industrial research and development.
