Abstract

We proposed the idea of a mixture by which the conductivity of the material under test is reduced so that it is possible to employ the cavity perturbation technique. Two simple but more practical mixture formulas for extrapolating the complex permittivity of a separate material through the measurement results of mixture are proposed and both are verified by measurement results. In addition, it is proved that the proposed mixture equations can be applied to predict the variation of the conductivity of the polymer as a function of the doping, which is always an interest of research workers in the field
