Abstract The rapid increase in electromagnetic interference has received a serious attention from researchers who responded by producing a variety of radar absorbing materials especially at high gigahertz frequencies. Ongoing investigation is being carried out in order to find the best absorbing materials which can fulfill the requirements for smart absorbing materials which are lightweight, broad bandwidth absorption, stronger absorption etc. Therefore, this article introduces the electromagnetic wave absorption mechanisms and then reveals and reviews those parameters that enhance the absorption performance.

The electromagnetic and radio-absorbing characteristics of ferrite-polymer composites with conductive inclusions based on polyvinyl alcohol are investigated. The Ni-Zn spinel ferrite powder of 2000NN grade with composition Ni0.32Zn0.68Fe2O4 was used as filler. It is shown that the obtained composites are effective absorbers in the frequency range of 2⸺5 GHz with peak reflection loss less than –20 dB. Through the analysis of the permittivity spectra and permeability spectra, as well as the calculated reflection loss spectra, critical factors of the electromagnetic wave absorption in obtained composites are established.
