Paper Abstract

In this paper, we present the design and experimental results of wide-band composite microwave absorber fabricated using thermoplastic polyurethane, carbon fibers, glass microballoons, micro and nano size magnetic materials. Ni-Zn ferrite and carbonyl iron powders of nano and micrometer size particles were used along with carbon fibers and microbaloons for the development of the absorber. It is found that both Ni-Zn ferrite and carbonyl iron powders and their ratio in the composite plays critical role in the absorber performance. Measured results show that a reflectivity reduction of 15 dB from 5 to 18 GHz is possible using this composite absorber.
