Electromagnetic Energy Deposition in a Concentric Spherical Model of the Human or Animal Head.

Abstract

A five-spherical layer plus core sphere, approximating the human or animal head, is exposed to plane wave, nonionizing electromagnetic radiation. The resulting induced fields within the simulated cranial structure are used in calculating the internal absorbed-power density distributions, average absorbed-power density, and total absorbed power. The mathematical theory and formulas basic to accomplishing the computations are discussed in depth. Calculation requirements encountered are implemented in the form of a computer program. Discussion of this users-oriented program covers such details as: structure and sequence of control parameter and data cards, output formats, and subroutine and function subprograms. Sample printouts and plots (linear and contour) of computer results and a listing of the FORTRAN source program are included. (Author)
