Setting and physical rationale of heterogeneous turning scatterer system mesh optimization

摘要

Simulation process of electromagnetic waves diffraction formulated in terms of MoM solution obtaining, as the first step of general meshing algorithm. As a scattering surface perfect conductor cylinder served. The task is complicated by the existence of a special inhomogeneity on the scattering surface, the presence of which must be well established as the result of scattering pattern analysis. Inhomogeneity is defined by the limiting case - through hole. Simulation describes the dynamic system wherein heterogeneity rotated relative to the cylinder axis. Physical origins of optimization parameters - morphology dependent resonances (MDR) provisions, within which special tunning cycle realized. Method of dynamic simulation - stepping movement of the object. The proposed algorithm has been tested in CAD, optimization results provide a significant gain in the specified accuracy, corresponding to standard CAD meshing rules.
