Study on numerical flux of node DGTD method:TM case
摘要
Abstract
The main difference between the discontinuous Galerkin time domain (DGTD)and the fi-nite element time domain (FETD)is the exchanging field by numerical flux.Based on the weak form solu-tion of TM case in 2D,the physical meaning of numerical flux and the different express between main unit and adjacent unit are firstly described.And then,combining the above,the DGTD iterative formulae are obtained.Finally,numerical examples of line source radiation and interference are given to demonstrate the validity of DGTD algorithm.关键词
