   Abstract:
   A hybrid discontinuous Galerkin spectral element and finite element time domain (DG-SE/FETD) method for the first-order Maxwell's equations is proposed in this study. It uses EB to replace the EH scheme in earlier research. The discontinuous Galerkin method is employed for domain decomposition. Non-conformal mesh allows not only an abrupt change of element size but also different element type across the interfaces between adjacent subdomains. Compared to EH scheme, the EB scheme has less DoFs, consequently, consumes less CPU time and memory. This new DG-SE/FETD method has been successfully applied to multiscale problems.
