用谐振腔法分析双侧鳍线的不连续性

本文将谐振腔法结合 Raleigh-Ritz 法与场源变分技术推广应用于分析双鳍线的不连续性,并以单侧——双侧——单侧级联鳍线不连续性为例,对两面不连续性同时选择两个基函数进行精确分析。作为分析结果,本文给出了其 T 型等效电路参数的一组数据,与已发表的数据比较,一致性较好。

Analysis of Bilateral Fin-line Discontinuity with Resonant-cavity Method

In this paper,a bilateral fin-line discontinuity is analysed by the resonant-cavity method combined with Raleigh-Ritz and variational techniques.As an example,a structure consisting of two cascad transitions between unilateral and bilateral fin-line has been investigated,in which,two basic functions are selected in both discontinuous bilateral fins.Based on the present analysis,the parameters of its equivalent T-circuit are obtained.They are in good agreement with the data published.
