Abstract

A set of FDTD numerical experiments is presented for a homogeneous spherical head and a simple dipole, in order to quantitatively assess the effect of antenna numerical representation and absorbing boundary conditions on simulated parameters of interest, referring to both dosimetric and antenna performance studies. A semi-analytical technique based on the theory of dyadic Green´s function in conjunction with the method of auxiliary sources is used for further validation and comparison of the FDTD results.
