Diffraction of the surface H-polarized wave by an angular break of a thin dielectric slab

Abstract

This paper deals with a recent advance in applications of the Sommerfeld-Malyuzhinets technique to the problem of diffraction of a surface wave by an angular break of a thin material slab. The solution is represented by Sommerfeld intergrals, which are then substituted into boundary conditions. The unknown spectral functions satisfy coupled Malyuzhinets functional equations. The latter are reduced to Fredholm second kind integral equations, which are solved numerically. The scattering diagram of the cylindrical wave arising from the edge of the structure is computed.
