摘要
本文采用边界元法对鳍线结构进行了混合模分析,该方法具有推导简单,计算量小,处理问题灵活等特点,它可对各种鳍线进行研究,其中包含鳍的厚度,波导模深度,不对称结构及具有多种介质等。文中对几个典型的例子进行了计算,得到的数据均与其它方法的结果相吻合。
A boundary—element method is presented for the investigation of finline structures which may include finite strip thickness, substrated supporting grooves, asymmetric structures, and more than one dielectric region, and a generalized finline configuration is studied thoroughly. To show the validity and usefulness of this approach, a few interesting examples are given. The obtained results have fairly good accuracy, and agree well with data available in the literature.
