Dosimetric analysis of plane wave propagation in biological tissues. Comparison between planar multilayer vs realistic anatomical models

Millimeter-wave wireless power technology is assuming increasing importance in everyday life, particularly with the recent advancements in the 5G communication systems. A numerical assessment of the exposure to such kind of sources allows to understand the interaction with the human body and to ensure compliance to guidelines limits. Due to the small penetration depth of the millimeter-waves, analytical models with simplified geometries are preferred to study such type of exposure. In this work we considered exposure of the wrist, with the aim to investigate whether these simplified models can be considered as a good representation of the human body, by comparing them with realistic anatomical ones. Results showed that a simplified slab model can lead to differences in the induced E-field along the entire section of the wrist.
