ABSTRACT:
An absorber for radiation of frequency of the order of 1 THz is formed of a body of cured silicone-based elastomer containing an inert, powdered siliceous filler. Both the elastomer and the filler are electrically insulating and the surface of the absorber that is exposed to the radiation is preferably profiled to enhance absorption of the radiation. The profiling preferably takes the form of an array of sharp-pointed pyramids having rectangular or triangular bases. A method of moulding such absorbers is also disclosed.
