Extraction of granular type material (GTM) permittivity at microwave frequencies

Permittivity of granular type material (GTM) is determined by waveguide reflection/transmission method which is considered most accurate in dielectric material characterization. In this process, GTM is mixed with another host medium. In the simulation, GTM and host medium both are assumed to have known value of complex permittivity and GTM permittivity is extracted from the observed linear relationship between volume fraction of GTM and composite (GTM+host) permittivity.
