Numerical Exposure to Realistic and Planar Body Models: Effect of the Polarization

In this paper, a comparison of the electromagnetic field induced by plane wave exposure with circular and linear polarization on an anthropomorphic human body model is shown. The same exposure was reproduced on a multilayer model. In particular, the anatomical region of the arm is analyzed and the frequency of 24 GHz is considered. The software used for these two sets of simulations are Ansys HFSS (for the multilayer slab model) and Sim4Life (for the anatomical model). The results show that differences in the EM field distribution (comparing the different polarization conditions) are visible with the 3-D simulations on anatomical models, while the layered model, as expected, is not sensitive to the change of polarization of the wave with normal incidence on the layering.
