| 摘 要： | 本文用混合模展开鳍线中的本征场,并应用谱域法确定主模和高次模的传播常数和谱域中的本征场,然后结合模匹配法分析鳍线阻抗不连续性的混合模散射特性。文中给出计算的单鳍前30个模,双鳍前20个模的传播常数和阻抗不连续性的主模散射参数,计算结果与文献发表的结果一致。有关数值收敛性问题亦在文中进行了讨论。

| Abstract: | The eigenfields in finline are expanded in terms of the hybrid modes. The propagation constants of the dominant mode and the higer modes as well as the associated eigenfields in the spectral domain are then determined by using the spectral domain method. Finally the hybrid-mode scattering characteristics of finline impedance discontinuities are analysed in combination with the mode-matching technique. The propagation constants of the first 30 modes in unilateral finline and the first 20 modes in bilateral finline as well as the scattering parameters of the impedance discontinuities are computed. The computed results agree well with the published data. The problems about the numerical convergence are also discus-sed. |
