abstract

  • We propose a fully overlapping domain decomposition method (DDM) for the analysis of small radiating/receiving features situated in electrically large enclosures for EMI/EMC analysis. The proposed method decouples the relatively dense finite element mesh (representing the RF environment of low-noise amplifier front ends and/or output power amplifiers with high fidelity), from a coarse background mesh modeling propagation and coupling effects with enclosures and nearby cable bundles. This overlapping decomposition allows for unstructured meshing of the small features within large domains, providing great flexibility in modeling multi-scale electromagnetic environments. We also demonstrate a higher-order version of the proposed method to further improve computational efficiency. © 2011 IEEE.
