Influence of the homogenization of tissues on the electric field calculation in numerical dosimetry for wireless application

This paper presents a new approach which allows to decrease the computation volume and the simulation time in dosimetric problems. This method uses a larger segmentation for the electric field calculation and an appropriate technique to assess the Specific Absorption Rate (SAR) induced into biological structures. To validate this approach, a 1D multilayer structure is exposed to a plane wave or to a dipole operated at 900MHz. Then, a realistic case is studied with a 3D child head model exposed to a plane wave. For this latter case, the segmentation is changed from 1mm to 2mm.
