The article considers a problem of electromagnetic wave diffraction on a nonplanar screen located in free space. The problem is reduced to an integral equation. The author has applied the Galerkin method for solving integral equation with the “Rooftop” basic functions. The article also considers the application of the subhierarchical method for solving integral equations and introduces the numerical results.
