Abstract

Numerical computations of different diffraction representations for the canonical wedge-scattering problem are discussed. Representations include total-field exact series summation, exact diffraction integral, and the Physical Optics (PO), Physical Theory of Diffraction (PTD), and Parabolic Equation (PE) techniques, and the Uniform Theory of Diffraction (UTD). Numerical challenges and advantages of each are given.
