Abstract

The finite-difference time-domain (FDTD) method is applied to obtain the three-dimensional (3-D) dyadic diffraction coefficient of infinite right-angle perfect electrical conductor (PEC) wedges illuminated by a plane wave. The FDTD results are in good agreement with the well-known asymptotic solutions obtained using the uniform theory of diffraction (UTD). In principle, this method can be extended to calculate diffraction coefficients for 3-D infinite material wedges having a variety of wedge angles and compositions.
