Computer-Based Permittivity Measurements and Analysis of Microwave Power Absorption in Conductive Dielectrics

The time domain reflectometer technique is applied to measure the dielectric properties of a pure Debye dielectric mixed with various amounts of salt. The effect of ohmic conductivity on a Debye dielectric is studied as a function of temperature and frequency. A computer simulation technique is used to compare the heating pattern in a conductive dielectric for two microwave absorption frequencies of 2.45 GHz and 915 MHz.
