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.
