Abstract
A simplified analysis of the evaluation of the dielectric parameters of materials at microwave frequencies using a cavity perturbation technique employing the E010 mode is presented. Expressions for the dielectric constant epsilon ' and dielectric loss epsilon are obtained from a single approach. The present analysis reveals the dependence of the dielectric parameters upon the ratio of the specimen and cavity dimensions. The final equations for epsilon ' and epsilon are in terms of experimentally measurable quantities and the evaluation involves only the use of the tables for Bessel functions Y0(z), Y1(z), J0(z) and J1(z) for complex arguments. The results are in very good agreement with those reported in the literature.
