摘要：
A novel non-overlapping and non-conforming domain decomposition method (DDM) based on volume-surface integral equation (VSIE) is presented for the electromagnetic analysis of complex Dielectric/Metallic Composite Targets. In this scheme, such composite objects are decomposed into multiple composite subdomains. To model efficiently subdomains involving very thin dielectric, the VSIE with simplified prism vector (SPV) basis functions is applied. Further, a discontinuous Galerkin volume integral equation method (DG-VIE) is used for conformal as well as non-conformal volume discretizations. For PEC parts, a discontinuous Galerkin surface integral equation approach is utilized. Several numerical examples are reported to demonstrate the accuracy and efficiency of the presented method.
