Wiener-Hopf method in problems of plane wave diffraction by two opposite staggered perfectly conducting half-planes

Diffraction of a plane wave on two opposite staggered perfectly conducting half-planes is considered using the Wiener-Hopf method. The Neumann boundary value problem is reduced to solving a system of Fredholm integral equations of the second kind, the solution to which is expressed analytically through the integral operator in the form of the sum of the Neumann series.
