Notes:
Composite electromagnetic wave absorbers made of a soft magnetic material (permalloy or sendust)and polystyrene resin were investigated [1]. The volume mixture ratio of magnetic material was variedin the range from 18 vol% to 75 vol%. The composites with the low volume mixture ratio ofsoft magnetic material absorbed more than 99 % of electromagnetic wave power in the frequencyrange from 1 GHz to 10 GHz. The values of the real part [removed info]r’ of the relative complex permeability [removed info]r*for both magnetic materials were less than unity at frequencies above approximately 6 GHz as thevolume mixture ratio of magnetic material increased. This result suggests the possible realization ofan electromagnetic wave absorber that can operate above 10 GHz
