Computation of the Electromagnetic Field with an Improved 2D FDTD Algorithm When Using Planar Applicators in Microwave Hyperthermia

In this paper, the electromagnetic field in biological tissues during microwave hyperthermia is computed by using an algorithm combining the SDA and the FDTD methods. The planar microstrip-microslot applicators as well as the surrounding heterogeneous tissues are seen to be guided structures where all electromagnetic fields are computed. Measured and computed results show a good agreement.
