| Summary: | Background. The purpose of the work is to develop and implement the parallel
algorithm for numerical solving the problem of electromagnetic wave diffraction by
non-planar perfectly conducting screens.
Materials and methods. Vector integro-differential equation of the diffraction
problem is considered; basis vector functions on non-planar parameterized screens
are introduced; the Galerkin method is used to find approximate solutions of the
problem.
Results. The Galerkin method is implemented using the MPI interface;
computational experiments are performed; efficiency of parallelization of the
numerical method is analyzed.
Conclusions. The results of numerical tests confirmed the convergence of the
Galerkin method and usefulness of using parallel algorithms for solving complex
vector scattering problems. |
