| 摘 要： | 本文提出了一种求解波导本征问题的非正交频域有限差分(FD-FD)算法。该算法中的数值离散网格可与任意复杂边界形状吻合一致。文中通过所建立的本征方程对波导中各模式的截止频率进行了求解,数值结果与已有结果符合良好。

| Abstract: | A finite-difference frequency-domain(FD-FD) method in non-orthogonal coordinate is presented for the eigenvalue problems of waveguide. The numerical discrete mesh of the algorithm can fit the arbitrary boundary well. In this paper the cut-off frequencies of modes of waveguides are calculated via given eigenvalue equation. The results show good agreement with those from other sources. |
