- Abstract:
- An efficient numerical simulation technique is introduced to extract the propagation characteristics of a millimeter guided wave structure. The method is based on the application of the Krylov subspace model order reduction technique(Padé via Lanczos)to the compact finite difference frequency domain(FDFD)method. This new technique speeds up the solution by decreasing the originally larger system matrix into one lower order system matrix. Numerical experiments from several millimeter guided wave structures demonstrate the efficiency and accuracy of this algorithm.
- 提出了一种十分有效的提取导波结构传播特性的数值方法. 它的基本思想是把Krylov子空间的模式缩减技术(Padé逼近/Lanczos分解)使用在紧凑格式频域有限差分法上, 把大的系统矩阵降阶为很小的系统矩阵, 从而加速了矩阵的运算求解.通过对几种导波结构的分析及和其他方法的比较, 证明了这种新方法的准确性和高效性.
