Electromagnetic Calculations using the FDTD-Method for the Analysis of Waveguide Applicators for Microwave Hyperthermia

Abstract

Electromagnetic calculations for waveguide applicators using the Finite Difference Time Domain (FDTD) method are presented. The algorithm is applied to a water-filled applicator and the computed results are compared to experimental results in a phantom of saline-solution. Influence of the loading on the near field of the applicator is illustrated in the case where a thin plexi-glass plate is inserted between the applicator and the phantom.
