Improvements in Techniques of Microwave Thermography
Abstract
During the period 15 November 1983 to 15 November 1984 our efforts have focused on (1) modifying our 3 and 6 GHz radiometers for reflection compensation and making design changes to improve the stability, (2) designing antennas to give improved penetration depth, and (3) bistatic measurements whereby the scattered radiation from an embedded object is determined to provide information on the size of the object and the proper frequency for hyperthermia. Measurements have shown that use of large-aperture antennas are directed toward utilizing the resonances which occur in the back scattered radiation as a function of the size of the scatterer and the wavelength of the radiation to establish the size of the scatterer and the optimum frequency at which maximum absorption will occur.
