Abstract

The paper reviews some integral methods used in static, low frequency (LF), and high frequency (HF) dosimetry, respectively, and biomedical applications of electromagnetic fields. Laplace equation/Boundary element method (BEM) is applied to certain electrostatic and LF exposure scenarios. Surface Integral Equation (SIE)/Method of Moments (MoM) and tensor volume integral equation/MoM and Stratton Chu integral formulation coupled with vector Helmholtz equations/hybrid Boundary element method (BEM)/Finite element method (FEM) scheme are used to analyze the exposure to HF radiation. In addition to human exposure to undesired electromagnetic radiation sources, this work also deals with biomedical applications of electromagnetic fields, by using SIE/MoM approach. Some illustrative numerical results for induced current densities, electric field and SAR, are also given in the paper.
