Abstract
Abstract : During the period 15 November 1982 to 15 November 1983 our research has been concentrated in two areas: (1) the design, construction, and testing of a reflection-compensating radiometer, and (2) a theoretical investigation of the variation of microwave penetration depth in human tissue as a function of the aperture size of the contact antenna. The radiometer operates at 1.4 GHz in the unbalanced mode and gives the reflection coefficient and the microwave temperature of the emitter corrected for reflections. The penetration depth of microwaves in body tissues depends critically on the aperture size and is significantly less than the penetration depth computed from the usual plane wave (or far field) approximation. Keywords: Microwave thermography.
