The constantly increase in use of devices operating at electromagnetic (EM) frequencies in our immediate environment, such as radar and wireless and mobile communications, has resulted in a great increase in EM interference, as well as in the intensity of this ever-more-present non-ionising radiation. The has lead to a growing requirement for MW absorbing materials to reduce interference, shield equipment, shield rooms and chambers for EM compatibility (EMC) testing, and to minimise the harmful effects of EM waves on biological tissues. Absorbers can be produced as ceramics or coatings. The EM properties of coatings can be effectively tuned simply by varying the volume fractions of the constituent phases.
