摘要
将区域分解法（ＤＤＭ）应用于电磁场问题分析，计算了准ＴＥＭ传输线的特性阻抗，并通过数值试验研究了区域分解法的收敛性及计算效率。利用区域分解法的优越性，在划分的几个规则子区域上引入ＦＦＴ快速算法，分析了矩形同轴线的特性阻抗。数值结果表明，区域分解法降低了计算复杂性、减小了计算规模，且提高了计算效率。
This paper presents domain decomposition method which is applied in the analysis of electromagnetic problems. The characteristic impedance of quasi TEM transmission lines are calculated by this method. The convergence property and computational efficiency of DDM are studied. The characteristic impedance of rectangular coaxial line is computed by fast Fourier transforms on divided several regular domain. The numerical results obtained show that DDM reduce both the computational complexity and computing time.
