To deal with randomness and uncertainty problems, an adaptive discontinuous Galerkin time domain (A-DGTD) method is proposed to quantify the influence of defect factors. In order to prove the efficiency of the method, the standard statistical analysis is performed to calculate the mean of reflection coefficients caused by random/uncertain physical parameters on a dielectric slab.
This paper presents an adaptive mesh methodology to construct simulation source which has unlimited spectrum coverage for the discontinuous Galerkin time-domain (DGTD) method. The limitation of grid size (i.e., λ/20) for the construction of time-domain signal is relaxed by using a nonuniform sampling technique. The excitation source is modeled by using a standard gauss pulse with a nonuniform sampling...
Discontinuous Galerkin finite element method (DG-FEM) for electromagnetic simulation is implemented using the Julia language in this work. DG-FEM is a combination of finite element method and finite volume method and it employs high-order spatial and temporal basis to obtain high-order accuracy. Julia is a relative new language specially built for high performance computing. It is adopted in DG-FEM...
