- Аннотация: The purpose of the work is the development, software implementation, and testing of a projection method and a parallel algorithm for solving the problem of electromagnetic wave diffraction on a system of solids and screens. Galerkin method is implemented for the vector integrodifferential equation of the diffraction problem; basis vector functions on a three-dimensional body and a parameterized nonplanar screen are determined; parallel algorithm for solving the problem is implemented using the MSMPI library. Approximate solutions to the model problem are compared with the previously published results; the inner convergence of the Galerkin method is investigated; dependence of the solution in the area of inhomogeneity on a perfectly conducting screen is investigated. The proposed technique of approximation of solutions on a curvilinear screen is an effective method that significantly expands the class of diffraction problems solved by integral equations method; numerical tests have confirmed high efficiency of the parallel algorithm.
