ABSTRACT:
An absorbing assembly for absorbing electromagnetic radiation in the range 10 MHz to 100 GHz comprises a lossy dielectric material and chiral elements disposed outside the lossy dielectric. The chiral elements may be springs, Mobius bands, irregular tetrahedra, tapering helical springs or handed non-planar forks. The lossy dielectric material may be in the form of a shaped structure e.g. for use in an anechoic chamber.
