In this paper, fundamental investigations of human shadowing at 60 GHz are presented. Different electromagnetic models are analyzed regarding their accuracy and computional effort. Therefore, different geometrical representations of the human body, namely circular cylinders with different dielectric properties, the dielectric elliptic cylinder, and the so-called multiple knife edge (MKE) model are investigated. Based on these models, the influence of the object shape on the modeling accuracy and the necessity of taking into account the human skin or clothing are estimated. In addition, a comparison of Doppler spectra based on measurements and UTD simulations is presented.
