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.
In order to determine the acceptability of dielectric coating, uncertainties estimations of reflection coefficients are studied using discontinuous Galerkin time domain (DGTD) method. According to the probability statistic theory, the mean and variance of reflection coefficients are calculated. The computed quantities of interest are compared with analytic solutions, and good agreement for the statistics...
In this paper, the electromagnetic computation and simulation of a cavity filled with vacuum and dielectric are discussed. An efficient discontinuous Galerkin time domain (DGTD) method which employs an orthonormal basis (for spatial discretization) and Runge-Kutta method (for temporal integration) to solve Maxwell's equations is given in detail. Numerical experiments on different order of approximation...
