Long-wavelength analysis of near-field irradiation of prolate spheroidal models of man and animals

Expressions are derived for the induced internal electric fields and average specific absorption rate (s.a.r.) in prolate spheroidal models of man and experimental animals irradiated by electromagnetic (e.m.) fields having arbitrary orientation and arbitrary impedance. These expressions are of value in estimating the s.a.r. in man and test animals exposed to e.m. near fields when the wavelength is long compared to the dimensions of the body.
