Abstract :
A finite difference (FD) solution to the problem of high-frequency scattering from a perfectly conducting wedge of arbitrary external angle illuminated by a Gaussian beam is presented. The solution is obtained through the application of the parabolic equation method. The solution is compared with the analytical asymptotic solution available in the literature
