Finite Element Numerical Experiments on the Absorption of the EMF Radiation in 3D Human Head Models

Intesive usage of cellular phones has increased the public concern about their possible health hazards. Experimental as well as numerical approaches has been used in order to evaluate the biological effects. Most of the papers used the finite diference time domain(FDTD) and the MoM (method of moments) numerical methods This paper deals with the computation of the local peak SAR and absorbed power values using the finite element method. Three spherical models have been taken into account: homogenous and layered. They were exposed to a dipole antenna operating at different frequencies and different distances. The results were compared with those from the literature and a good agreement was obtained
