This paper presents characterization and modeling of microwave characteristics of SiC foam material. Transmission and reflection measurements are performed in X, K and Ka band for the samples of two different pore sizes and three different thicknesses. Effective and frequency dependent dielectric permittivity is extracted for 50PPI 10 mm sample, while for the other samples it was not possible because of density gradient in the samples. By calculation of Mie scattering efficiencies approximate magnitude of dominant loss mechanism (scattering or absorption) at certain frequencies is predicted.
