鳍线特性的计算机分析

Computer Aided Analysis of Fin Line Characteristics

本文给出谱域法分析鳍线相位常数和特性阻抗的原理、程序及某些数值结果。由谱域法得到鳍线基模和高次模的相位常数和场分布,在此基础上,进一步给出模匹配法分析鳍线纵向不均匀性的公式、程序和某些计算结果。

The spectral donain technique is used to derive phase cons ant and field distributions of both dominant and higher order modes of unilateral fin line structures. Charaeteristic impedances based on the power-voltage definition are calculated. Furthermore, one kind of discontinuities(notch)in the slot width of fin lines is analysed and calculated typically, with higher order modes beirg taken into account. Numerical results agree well with the experiments done by the authors.
