摘要
文中基于加权因子、中心差分及场平均技术，从Ｍａｘｗｅｌｌ方程出发导出了对称压缩顶点传输线矩阵法的一种新格式。针对这种新的传输线矩阵法，给出了其稳定性条件以及在导体表面、介质分界面上的连结条件。
This paper presented a new scheme of the TLM symmetrical condensed node(SCN) from Maxwell’s equations by using weighting factor, centered difference, field averaging.The node scattering matrices and field expressions are given for the general case with graded mesh and anisotropic materials including electric and magnetic losses. The stable conditions of this new TLM scheme are derived. The validity of this new scheme is verified by numerical examples.
