摘要
利用积分方程方法进行复杂导体目标电磁散射特性分析必须综合考虑电磁问题和几何外形的共同建模 ,几何建模是电磁建模的基础 ,直接关系到电磁计算的精度与复杂度。建立复杂目标的几何外形需按照一定的原则对目标进行网格划分。本文针对复杂导体目标提出了几何建模和网格划分的原则 ,利用ANSYS的APDL语言建立了复杂目标的几何模型 ,以roof top基函数和曲面RWG基函数为例 ,给出了符合电磁计算要求的几何数据。
The geometry construction of complex objects needs to be firstly considered when calculating their electromagnetic scattering with Integral Equation Method. It is the base of the electromagnetic analysis, determining the accuracy and the time consuming directly. The object should be set up and be meshed according to some rules before electromagnetic analysis. This paper recommends some rules about the PEC objects′ geometry construction and surface meshing, builds some complex objects through ANSYS′s APDL language, and gives the proper meshing data suiting for roof-top basis function and curved RWG basis function for instance.
