ABSTRACT:
A conformable electromagnetic radiation suppression cover comprising one or more absorbing material(s) and a sealant. The cover conforms to the shape of a reflecting structure due to forces internal to the absorbing material(s) when the cover is subjected to an agent external to the cover. The absorber comprises dissipative particles bound in a conformable polymeric binder. The sealant is positioned to seal the conformable cover to the reflecting structure, and provides environmental protection to the structure and preferably better adhesion between the cover and the structure. In a preferred embodiment, the volume of the cover is varied before shrinkage to produce a cover thickness in the direction of incident radiation, as measured after shrinkage, which produces a preselected resonant frequency for the cover. The cover may include a conductive surface, such as a metallic foil. Impedance matching materials are preferred but not required.
