The aim of this paper is the investigation of the numerical properties of the boundary element method (BEM) when applied to dosimetric analysis of human exposure to electromagnetic fields adopting high resolution voxel-based data sets. Some test problems are analyzed considering the neck region of the human body radiated by a loop antenna. Different strategies in the development of the problem equations are proposed and their effects on the conditioning of the BEM matrix are discussed. Several direct and iterative solvers are applied to the model problems and their efficiency is compared.

Abstract
The aim of this paper is the investigation of the numerical properties of the boundary element method (BEM) when applied to dosimetric analysis of human exposure to electromagnetic fields adopting high resolution voxel-based data sets. Some test problems are analyzed considering the neck region of the human body radiated by a loop antenna. Different strategies in the development of the problem equations are proposed and their effects on the conditioning of the BEM matrix are discussed. Several direct and iterative solvers are applied to the model problems and their efficiency is compared.File in questo prodotto:
