提出了一种有效分析复杂环境中电磁波辐射和散射的混合有限元方法和高频技术。它利用有限元方法对特征较小和复杂的区域进行分析，并利用高频傅里叶变换对结构中的电大尺寸目标进行分析，同时考虑了有限元域与高频技术分析目标之间的相互作用。给出了用物理光学作为高频技术分析二维散射和辐射问题的结果，说明了该方法的主要特点。
A hybrid finite element method (FEM) and high frequency technique (HFT) for the efficient analysis of the radiation and scattering of electromagnetic waves on complex environments is presented. It makes use of FEM for the regions with small and complex features and a HFT for the analysis of the electrically large objects of the structure, taking into account mutual interactions between the FEM domains and the objects analyzed with HF techniques. Results of the analysis of two-dimensional scattering and radiation problems using Physical Optics as the high frequency technique are given showing the main features of the method.
