A UTD Elliptic Cylinder Model for Studying Body Orientation Influence on Human Blockage

Nowadays, Human Body Shadowing (HBS) prediction is of prevalent interest for wireless communications, especially for millimeter waves (mmWaves), Wireless Body Area Networks (WBANs), and pedestrian crowds in dense urban environments. In this paper, HBS is predicted using a propagation model based on an elliptic cylinder (with or without a sphere for the head) for the human body geometrical model and Uniform Theory of Diffraction (UTD) for the associated electromagnetic theory. Indeed, this kind of model can be useful to study body orientation influence on human blockage phenomenon. Moreover, to analyze the contribution of such a model, we also compare it with UTD single circular cylinder models and with 2.4 GHz radio measurements coupled to Motion Capture (MoCap).
