An Embedded Domain Decomposition Method for Time-Harmonic Electromagnetic Problems
This paper introduces a finite element based embedded domain decomposition method (DDM) for time-harmonic Maxwell’s equations. 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 subdomains, thus offering great flexibility for electromagnetic modeling and design.
