SCATTERING AND ABSORPTION OF MICROWAVES BY DISSIPATIVE DIELECTRIC OBJECTS: THE BIOLOGICAL SIGNIFICANCE AND HAZARDS TO MANKIND

Abstract

The relative absorption cross section of mankind exposed to nonionizing microwave radiation was determined using doll and sphere phantoms whose electrical properties simulated those of a human being. The investigation proceeded in three stages of increasing difficulty: (1) theoretical and experimental study of homogeneous phantoms, having the electrical properties of muscle tissue; (2) theoretical studies of two-layer phantoms, having the electrical properties of muscle tissue and subcutaneous fat; and (3) ex trapolation to three-layer phantoms, having the electrical properties of muscle tissue, subcu taneous fat, and skin. The investigation at each stage resulted in certain generalizations which could be used as a guide to the investigations at the succeeding stage. In this way both the theoretical and experimental work necessary was simplified. The final stage involved a synthesis of all the previous work so that the relative absorption cross section of mankind could be predicted with confidence for the total frequency range from 400 to 10000 Mc/s.
