The paper investigates diffraction at trilateral cylinders with combinations of soft (electric) and hard (magnetic) faces. Scattered field in far zone is calculated according to the physical theory of diffraction. The first-order high-frequency appro

Physical theory of diffraction (PTD) is developed for the field scattered at a perfectly conducting rectangular plate. Grazing incidence and grazing scattering are analyzed. High-frequency asymptotic estimations are derived. Bistatic and monostatic s

Fringe waves represent the diffracted field generated by the nonuniform/fringe surface currents concentrated in vicinity of sharp scattering edges. For perfectly conducting wedges, they have been studied in a number of publications. In this communica

Basic features of the modified theory of physical optics (MTPO) are discussed on the example of scattering at perfectly reflecting half-planes and wedges. It is shown that violations of the geometrical optics (GO), introduced in this technique, resul

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 T

High-frequency approximation is constructed for backscattering from a strip with one face soft and the other face hard (i.e., with Dirichlet and Neumann boundary conditions, respectively). This approximation is based on the solution of the canonical

In our recent paper, we have discussed and shown that modified theory of physical optics (MTPO) violates the fundamental laws of GO and because of that does not satisfy the Helmholtz equation. Then, we have illustrated that MTPO fringe waves are inco
