ABSTRACT:
A highly effective barrier for protecting objects against focused beams of radiant energy. The invention has special applicability in a combat environment for protecting military equipment against destruction by laser weapons, or for thwarting detection of such equipment by reflected radar waves. The barrier comprises a layer of slitted and expanded metal foil, made from a non-ferrous metal having an absorptivity less than 3% and a thermal conductivity above 100 W/m/K, interposed between the radiant energy beam and the object to be protected. The barrier layer may be multiple sheets of the slitted and expanded metal foil, or a contained layer of nested ellipsoids formed from the expanded metal sheets.
