SAR Estimation in Human Head Models Related to TETRA, GSM and UMTS Exposure Using Different Computational Approaches
Author:
Abstract: The scope of this paper is to calculate the electric field both inside and outside the human head and consequently to estimate the Specific Absorption Rate (SAR) when an antenna is placed at its close proximity at TETRA, UMTS and GSM frequencies. The analysis is twofold: a semi-analytical approach based on three-dimensional Green’s function theory is initially implemented whereas a FEM (Finite Element Method) method is used in order to further validate the analysis, by simulating the relevant three-dimensional geometries. Numerical and simulation results are obtained for the local SAR values at different points inside the head when the model of the human head is exposed to the radiation of dipole antennas at 0.4GHz (TETRA), 0.9GHz (GSM), 1.8GHz (GSM) and 2.2GHz (UMTS) placed at a distance of 1 cm, 2cm and 3cm from the head model.
