源点在NURBS曲面上的UTD爬行波射线寻迹算法研究
reeping Ray-Tracing algorithm of UTD Method Based on NURBS Modeling with source on surface
为分析复杂模型中天线的电磁兼容问题，本文引入了NURBS曲面作为建模手段。针对工程实际中源点多处于物体表面这一现实情况，给出了源点位于曲面上的NURBS建模UTD爬行波寻迹算法，该方法可应用于单个贝齐尔面片上。数值结果表明，本文方法应用到典型模型时，所得结果与解析方法吻合良好，并可进一步推广应用到任意曲面模型.
o analysis the EMC problems among antennas on complex models, NURBS is introduced for modeling . Due to the fact that practically the source is always on the surface, a new creeping ray-tracing method of UTD based on NURBS modeling is presented in this paper. The method presented in this paper can be applied to single Bezier patch. The algorithm is applied to some typical simple models and get good results compared to analytical method, also the algorithm can be extended to apply on arbitrary surfaces.
