Abstract

High-frequency asymptotic (HFA) techniques are reviewed through a classical, canonical problem: electromagnetic wave scattering from a wedge-shaped object with perfectly electrically conducting (PEC) boundaries. The Physical Optics (PO) and Physical Theory of Diffraction (PTD) approaches are compared against the exact solution through many scenarios and illustrations.
