Numerical Methods for SAR Evaluation in Biological Bodies

Pietro L. Buccheri, Antonino Spagnuolo

Abstract


This paper deals with the development of numerical schemes devoted to the study of the energy absorption from biological body exposed to an external source of electromagnetic (EM) field. The specific absorption rate (SAR) distribution in a human head is evaluated by employing two different numerical schemes: the Method of Moments and the Finite Difference Time Domain method. The first one solves EM problem described by Green's integral Equations in frequency domain by replacing human tissues with equivalent free-space current density, while for the second one a direct numerical discretization of Maxwell's equations and constitutive relations in time domain are used.
