ABSTRACT:
Atomized metal particles distributed within a resin matrix form a composite that can be selectively heated by exposure to microwave radiations. The composites can also be formed into non-electrically conductive but thermally conductive dielectric and magnetic structures by appropriate selection of metal particles and matrix materials. In other applications, metal particles are gradually distributed within a layer of resin matrix to create an electro magnetic radiation-absorbing medium used in the fabrication of anechoic and shielding structures.
