Spectral Integral Method and Spectral Element Method Domain Decomposition Method for Electromagnetic Field Analysis
<p>In this work, we proposed a spectral integral method (SIM)-spectral element method (SEM)- finite element method (FEM) domain decomposition method (DDM) for solving inhomogeneous multi-scale problems. The proposed SIM-SEM-FEM domain decomposition algorithm can efficiently handle problems with …

Computation of multiscale time-harmonic electromagnetic radiation
… the equivalence principle algorithm (EPA) as a domain decomposition method (DDM). The use of EPA to enclose the EFIE-modeled antenna generalizes the method to arbitrary antenna models. The electrically large exterior structures are modeled with physical optics (PO) without loss of generality to …

Multiscale forward and inverse problems with the DGFD method and the deep learning method
… A deep learning based full wave inversion method has also been developed to reconstruct the underground anomaly.</p><p>Since the gas and oil industry has very high demands for the forward modeling speed when doing inversion, the inversion model is usually simplified to a 1D or 2D problem by …

Unified conformal/nonconformal domain decomposition methods for solving large-scale multi-region electromagnetic problems
… element tearing and interconnecting (FETI-DP) method for the full-wave analysis of large-scale electromagnetic problems in three dimensions. These algorithms are designed to expand the capability of the FETI-DP method to accommodate more flexible interface meshes, to achieve faster convergence …
