A Novel TD Dyadic Diffraction Coefficient for Arbitrary Polarized UWB Signals

In this paper, a new time-domain (TD) three-dimensional (3D) dyadic diffraction coefficient is presented for UWB signals with arbitrary polarization. Simulation results are presented for diffraction through building scenario which covers single and double diffraction. An excellent agreement of the presented TD solution with the inverse fast Fourier transform (IFFT) of the corresponding exact frequency-domain (FD) solution confirms the accuracy of the proposed solution. The proposed TD solution can be used to analyze multiple diffractions for arbitrary polarized signal with oblique incidence.
