摘要

考虑了一类二维(2D)问题。这个类通常被分析为三维(3D)问题。采用时域有限差分法分析了横向磁极化问题。未知的数量从3D情况下的6个未知减少到2D情况下的3个未知。减少未知的数量可以减少CPU时间和存储需求。本文给出了带状线、微带电路和波导结构的几个例子，以展示该技术在分析实际问题(如二维问题)时的简单性和通用性。通过将我们的结果与已发表的结果进行比较，验证了该解决方案。

Analysis of stripline and waveguide discontinuities as a 2D-problem using finite difference-time domain method

A class of two dimensional (2D) problems is considered. This class is usually analyzed as three dimensional (3D) problems. The finite difference-time domain (FDTD) method is used to analyze the problem of transverse magnetic (TM) polarization. The number of unknowns is reduced from six unknowns in the 3D case to only three unknowns in the 2D case. Reducing the number of unknowns reduced the CPU time and reduces the storage requirements. Several examples are presented for stripline, microstrip circuits, and waveguide structures to show the simplicity versatility of the technique for analyzing practical problems as 2D-problems. The solution is verified by comparing our results with published results.
