Abstract

The aim of this study was to evaluate and compare temperature distributions for different tissues being treated at the time of interstitial microwave hyperthermia. A coaxial-slot antenna implemented into the tissue is the source of microwave radiation. The described model takes into account the wave equation for the TM mode and the Pennes equation determining the temperature distribution within the tissue in the stationary case. The simulation results for the three fundamental microwave frequencies of tissue heating devices are presented.
