Abstract

The use of the resistive sheet for characterizing thin metallic films is presented in a microwave heating context. A finite edge element formulation is used to include the resistive sheet surface integral in both the frequency and time domains. The properties of the resistive sheet are compared with analytical expressions for the reflection, transmission and absorption coefficients and a correction factor is suggested to improve the accuracy of the numerical implementation. Results are presented for single and multimode systems.
