Abstract
A simple and compact gaussian beam launcher to produce a focused microwave field for selective Partial-body exposures in biological experiments is described. The proposed structure consists of a Potter's dual mode horn with slight modifications and the aperture of this hom is loaded with a dielectric sphere (lens). It is shown that the resulting diffracted field in the image-space of the lens is a near-circular gaussian-beam with a high focusing factor. The details of an X-band test launcher with measured and theoretical results are presented. The simplicity of the proposed structure enables a compact and light-weight design of the launcher at the diathermy frequency of 2450 MHz.
