Investigation on electromagnetic wave absorption behavior of Hard-Soft ferrite nanocomposite in the frequency range of 1-18 GHz

In this study, we investigate the electromagnetic wave absorption of Hard-Soft ferrite nanocomposites in the frequency range of 1-18 GHz. These composites consist of two different magnetic phases with different weight ratios. The hard magnetic phase consists of Strontium Hexaferrite (SF) and the soft magnetic phase consists of Cobalt Zinc Ferrite (CZF). XRD analysis of the samples indicate formation of pure phase for each magnetic phases. Investigation of the real and imaginary parts of complex permittivity and permeability of samples indicate the response of electromagnetic waves to these samples in the frequency range of 1-18 GHz. The reflection loss versus frequency shows this absorbing behavior in the samples.
