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