N2 - The frequency dependences of the relative complex permeability μr*, the relative complex permittivity εr * and the absorption characteristics for composite electromagnetic wave absorbers made of polystyrene resin and sendust (an alloy of Al, Si and Fe) or aluminum fine particles were investigated in the frequency range from 1 to 40 GHz. The size and volume mixture ratio of sendust and aluminum were varied. A metal-backed single-layer absorber made of sendust and that of aluminum absorbed more than 99% of electromagnetic wave power at frequencies above 10 GHz. Moreover, the values of μr* was shown to be controlled by adjusting the volume mixture ratio and particle size of sendust or aluminum, and an electromagnetic wave absorber with a flexible design was proposed.
