Multiscale Hybrid-Mixed Discontinuous Galerkin Time Domain Method for Time Domain Electromagnetic Calculation

There are more and more multiscale problems in recent years, the multiscale method has received a lot of attention. However there is pretty few researches about multiscale numerical algorithms in computational electromagnetism. A family of new multiscale finite element method called Multiscale Hybrid-Mixed method has many advantages to deal with the electromagnetic problems when it combine with Discontinuous Galerkin Time Domain (DGTD) method in the second level. In this article, MHM-DGTD method is used for the calculation of resonant cavity. We further explore the computational performance of this method. Moreover, we will apply the MHM-DGTD method to calculate electromagnetic problems with complex structure or microstructure in future work.
