Abstract :
A semianalytical solution has been presented for the power coupling between the waveguide applicators of a TEM concentric array radiating into a three-layered cylindrical tissue model of circular cross section. Scattering parameters indicating the effect of coupling via the radiating apertures of a eight element TEM concentric array have been computed and presented at the operation range of the system.
