摘要

提出了一种基于有限元的嵌入式域分解(DDM)方法，用于电磁兼容性分析。该方法将一个计算域分解为一个背景子域和多个嵌入子域。子域之间的信息交换是在它们的共享区域进行的，包括四个要素:场连续性、材料差异、完美电导体(PEC)和端口。该方法允许完全非共形子域，从而为电磁兼容和信号完整性应用中的建模和设计提供了极大的灵活性。

Electromagnetic Compatibility Analysis Using Embedded Domain Decomposition Method

A finite element based embedded domain decomposition method (DDM) is introduced herein for electromagnetic compatibility (EMC) analysis. In the method, we decompose a computational domain into a background subdomain and several embedded subdomains. Information exchange between the subdomains are addressed in their shared regions, including four ingredients: field continuity, material difference, perfect electrical conductor (PEC), and port. The proposed method allows for completely nonconformal sub domains, thus offering great flexibility for the modeling and design in EMC and signal integrity applications.
