Abstract

The interaction of microwave radiation with biological systems is influenced by the electromagnetic property of tissue media, specifically, dielectric permittivity and magnetic permeability. The frequency-dependent characteristics of the dielectric properties of biological materials may be described by the relaxation processes, displaying a time-dependent response to sudden excitation. This chapter describes the dielectric relaxation processes and presents summaries of the measured tissue dielectric permittivity data for dielectric constants and conductivities as functions of frequency and temperature. Since water is a major constituent of biological materials, tissues may be classified into three major groups according to their water content.
