Abstract :
Composites with carbon nanomaterial fillers are of interest for developing and producing cheap and effective structures for protection different systems from electromagnetic (EM) radiation. By this radiation one means, first of all, background EM noise, emitted by cellphones, microwave ovens, computers, etc. Different shielding efficiency for different purposes is needed. For example, attenuation efficiency more than 30 dB suffices for commercial application, but for military purposes - from 80 to 100 dB is necessary.
