Edge Green's functions on a multi-sheet surface. Asymptotics of solutions of
coordinate and spectral equations
A. V. Shanin M. V. Lomonosov Moscow State University, Faculty of Physics
Abstract:
The problems of of diffraction by a strip or a set of strips with ideal boundary conditions, as well as some other problems, can be reduced to the scattering problems on multi-sheet surfaces by applying the method of reflections. Further reducing of these problems can be achieved by applying the embedding formulae. As the result, the solution of the problem with a plane wave incidence becomes expressed through edge Green's functions, i.e. the fields excited by
dipole sources localized in the branch points of the surface.
The paper is dedicated to finding the edge Green's functions. Two systems of differential equations are derived to solve this problem, namely the coordinate and spectral equations. The proprties of solutions for those systems are studied.
