Electromagnetic wave Absorbing Materials

ABSTRACT

For specific application there is a need for materials which absorb the electromagnetic energy incident on them . These nonreflective electromagnetic wave (EM) absorbing materials are useful as radar absorbing materials (RAMs) as surface coverings in electromagnetic anechoic chambers etc . Their primary function is to absorb and dissipate the electromagnetic energy to which they are exposed so that the reflected and/or scattered electromagnetic component is significantly small. In RAM applications when a target is surface-treated with an absorbing material the radar echo is minimized facilitating an electronic countermeasure technique of low probability of detection of the target by the radar.
