Human body impedance model and human age dependence of dielectric properties

A cylinder model of human body bio-impedance was proposed and analyzed with equivalent circuits and simulation method, so as to get some hints for possible medical diagnosis and physiology information. Neighboring effect exist for subject body placed in transverse electromagnetic (TEM) chamber. Description was given on frequency range for in-body ultra-wide band communication channel, and on correlation between people age and electric parameters of permeability, conductivity in skin and muscles of human body.
