Abstract

The frequency dependences of the relative complex permeability μr* the relative complex permittivity and the return loss for the composite made of sendust flakes or spherical sendust particles dispersed in polystyrene resin were investigated in the frequency range from 1 to 40 GHz. The values of increased when sendust flakes were dispersed in polystyrene resin and the frequency dependence of μr* was different in the particles shape of sendust. Therefore, absorption characteristics depended on the particle shape of sendust and the absorption of electromagnetic waves with a wide bandwidth in the frequency range from 10 and 20 GHz could be achieved using spherical sendust particle with a low volume mixture ratio.
