A discontinuous Galerkin augmented electric field integral equation method for multiscale structure modeling

In this paper, a discontinuous Galerkin augmented electric field integral equation method (DG-A-EFIE) is presented to handle low-frequency, multiscale electromagnetic problems. The discontinuous Galerkin (DG) method allows non-conformal meshes. The augmented electric field integral equation method (A-EFIE) can eliminate the low-frequency unstable problem of EFIE. The presented DG-A-EFIE formulation is suitable for multiscale modeling. Numerical results verify the accuracy, efficiency, and flexibility of the DG-A-EFIE for multiscale modeling.
