Abstract
It is demonstrated that an aperture antenna, excited by a leaky wave, will transfer power into an homogeneous lossy half-space at levels exceeding expectation. However, such local enhancements are only possible in the near-field region in the central part of the array. With the proper choice of parameters, enhancements of the order of 15 dB can be achieved. The calculated results are relevant to hyperthermic heating in cancer therapy and to related problems in biological hazards
