Abstract

An integral method to correctly calculate the mutual coupling between a parallel-plate waveguide applicator and an inhomogeneous lossy structure is presented. The aperture field and hence the electromagnetic absorption in the biological structure are a result of this coupling. The results for the TE/sub 1/-mode excited parallel-plate waveguide applicator are presented. The possibility of changing the electromagnetic absorption in the biological structure by introducing a dielectric material in the waveguide is investigated.<>
