V. Anantha et A. Taflove, Calculation of diffraction coefficients of three-dimensional infinite conducting wedges using FDTD, IEEE ANTENN, 46(11), 1998, pp. 1755-1756
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.
