Abstract

CoFe alloy nanoflakes (NFs) with diameter and thickness on nanoscale are prepared by hydrogen-thermal reduction in Co[Fe.sub.2][O.sub.4] flakes and their effective complex permittivity and permeability are measured. The effective electromagnetic wave absorbing (EMA) band position of the coating with CoFe alloy NFs as fillers is located in the range of 2-4 GHz, while the effective EMA band position of the coating containing CoFe alloy NPs as fillers is located in the range of 8-18 GHz.

Abstract

A new method is described for calculating the intrinsic or effective permeability in composite media with low filler concentrations. The new method is tested in Fe/Si[O.sub.2] based composite media and a new way is proposed for extending the applicability scope of the Bruggeman effective media theory.
