摘要

A shooting and bouncing ray (SBR) based software is developed by the secondary development of Unigraphics (UG). The core algorithm of ray tracing is based on the optimized Non-uniform Rational B-splines (NURBS) curve-surface intersection algorithm built in UG, which results in very high accuracy of ray path tracing without meshing, thus keeping the accuracy of the original cavity model. It is also efficient even if work with a complex cavities because of avoiding of shielding process. Both geometry modeling of cavity and its scattering simulation are integrated into a uniform platform, which forms an easy-using integrative and universal environment for electromagnetic modeling of complex cavities. In this paper, the developed software for complex cavity scattering modeling has been introduced with some numerical results to demonstrate the accuracy and efficiency.
