Facet Model Processing for Complex Shape Object Scattering Calculation

Abstract

The problem of construction a facet model of complex shape object for simulation of scattering electromagnetic is considered. It is proposed to use the approach of raytracing and kd-trees in order to take into account the re-reflections between some parts of the object. An algorithm for simplifying the geometric model of the object is proposed in order to reduce the time necessary for modeling. Comparison of calculated fields for identical objects, but with a different number of facets, showed that combining facets accelerates the simulation without violating its accuracy.
