【摘要】 利用二维有限差分法对非对称屏蔽带状线的TE模式进行计算。通过调整网格数目观察计算结果的精度,可以设定出最优的网格数目,然后改变带状线带尺寸,观察最低两个TE模对应的截止频率的变化规律,最后给出对应的横截面电场、磁场分布图,并对划分网格数量和带状线的尺寸对最低两个TE模对应的截止频率的影响进行了分析。更多还原

【Abstract】 The TE mode of Unsymmetrical Shielded Strip-Line is calculated with two-dimensional FDM. According to the accuracy of the calculation results of different numbers of the mesh grid, the most appropriate mesh grid number is obtained. Then, by changing the size of the unsymmetrical shielded strip-line, the variation principle of the two lowest TE modes is analyzed. Finally, with the charts of the electric field and the magnetic field on the cross-section, the influence of the number of the mesh grid and the size of the strip-line on the frequency of the two lowest models is analyzed in this paper.更多还原
