Abstract :
We apply the FDTD method of Stratis et al. (1997) and Anantha and Taflove (1998) to numerically obtain the dyadic diffraction coefficients for several infinite 3-D right-angle material wedges over a range of observation angles and frequencies. This method exploits the temporal causality inherent in FDTD modeling, as discussed in Anantha and Taflove for the infinite perfect electrical conductor (PEC) wedge case.
