Green’s function for the Helmholtz equation in a polygonal domain of special form with ideal boundary conditions
M. A. Lyalinov St. Petersburg State University, St. Petersburg, Russia
Abstract:
A formal approach for the construction of the Green's function in a polygonal domain with the Dirichlet boundary conditions is proposed. The complex form of the Kontorovich–Lebedev transform and reduction to a system of integral equations is exploited. The far-field asymptotics of the wave field is discussed.
Key words and phrases:
diffraction by a double wedge with polygonal boundary, scattering diagram, integral equations of the second kind, Kontorovich–Lebedev transform, Sommerfeld integral.
