DG-FETD modeling of EM structures with waveguide excitations

The globally explicit DG-FETD method is developed to model the EM structures with waveguide excitations. The techniques of higher-order elements and conformal PML, and the LTS scheme are incorporated into the DG-FETD modeling. In addition, a novel approach is proposed to calculate the S-parameters. This approach avoids of pre-simulation of uniform waveguide. Validation of the DG-FETD modeling is performed. More formulation details and numerical results will be presented and discussed in the conference.
