Exact Solution of Problems of Diffraction of Unsteady Waves on a Wedge under Mixed Boundary Conditions by the Smirnov−Sobolev Method

Until now, the Smirnov−Sobolev method has been applied only to diffraction problems with the Dirichlet and Neumann boundary conditions. In this study, it is shown that the method also leads to an exact solution of the mixed problem of diffraction on a wedge, which is very important, for example, for estimating the possibility of protection from blast waves by wedge-shaped barriers with different reflecting properties of the sides.
