Hybridizing CBFM and ray tracing for on-body propagation

An extension of the Characteristic Basis Function Method (CBFM) for handling radiating problems involving structures with apertures (slots) is hybridized with a ray tracing based solver to characterize the propagation between a transmitting waveguide antenna and a generic receiver operating at 94 GHz, located in proximity of a human body. Specifically, CBFM is used to estimate the radiation pattern of the transmitter, which provides the radiation pattern model to be employed in the ray tracing solver.
