Book Description The problem of wave diffraction by wedge-shaped structures is important in many applications, including electromagnetics, acoustics and geophysics. Numerous attempts to solve these problems have been made during the last 70 years using both analytical and numerical methods, but this has proved to be very difficult; only a few.

It is the first reference on novel, highly efficient analytical-numerical approaches for wave diffraction by impedance wedges or cones.

Wedge Diffraction. For wedges of non-zero included angle a solution technique analogous to the Wiener-Hopf method was developed by Maliuzhinets (c). The solution is carried out in cylindrical polar coordinates and, for a wedge subject to first order (possibly different) impedance boundary conditions on the two faces, the method is simple and elegant (see Chapter 4).

It may seem surprising that we don't get a simple pattern like Figure \(\PageIndex{1b}\), but the pattern would only be that simple if the wavelength was hundreds of times shorter than the distance between the gaps in the barrier and the widths of the gaps.

Generally, the paper follows the historical order from Sommerfeld's early work to recent stochastic results - hindsights and. Overview The physical optics (PO) currents are discontinuous at any edge or other line discontinuity in the surface slope, and, since they are non-zero only over the illuminated portion of a body, they may also be discontinuous at a shadow boundary.
