Abstract: An essential task of channel modeling for vehicular communications and sensing applications is predicting scattering from traffic participants, here represented by complex-shaped curved bodies. One approach is to discretize the curved body into facets and then use Ray Tracing (RT), combined with the Uniform Theory of Diffraction, to find the scattered field. We show that more comprehensive diffraction methods are required to achieve realistic results: one of them is vertex diffraction, and its implementation in the RT framework is considered in this work. Simulations by thus augmented RT are compared with simulations by MLFMM and PO solvers for discretized spheres and a simplified car, respectively.
