Abstract
The problems of diffraction by a slit or a strip having ideal boundary conditions, and some other problems, can be reduced to the problem of wave propagation on a multisheet surface by applying the method of reflections. Further simplifications of the problem can be achieved by applying an embedding formula. As a result, the solution of the problem with a plane wave incidence becomes expressed in terms of the edge Green’s functions, i.e., in terms of the fields generated by dipole sources localized at branchpoints of the surface.
The present paper is devoted to finding the edge Green’s functions. For this problem, two sets of differential equations, namely, the coordinate and spectral equations, are used. The properties of solutions of these equations are studied. Bibliography: 9 titles.
