A new time-domain diffraction coefficient for non-perfectly conducting wedges

In this paper, a new time-domain (TD) diffraction coefficient for non-perfectly conducting wedges is proposed that is applicable to the case when the source illuminates either one or both sides of wedge for different wedge angles. The TD received field is compared with the inverse fast Fourier transform (IFFT) of frequency-domain (FD) solution. Finally considering hard polarization, the computational efficiency of both methods (TD and IFFT-FD) has been compared.
