Abstract :
A MW radiometric method for the study of the semiconductor properties of tissue is proposed. This method makes use of the non-linear properties of tissue in conjunction with its radiative properties as described by black-body theory. The region of the body under examination is illuminated by a monochromatic MW field which ´mixes´ with the MW field generated by this region. This ´mixing´ gives rise to an intermodulation spectrum (IS) which should be detectable by using a radiometer tuned to a predetermined difference frequency, or alternatively a sum frequency of the IS.
