双层介质鳍线色散特性的分析

The Analysis of Finline Dispersion characteristics with Two-Layer Dielectric

本文用直线法分析了双层介质单侧与双侧鳍线。根据电磁势矢量在均匀域的转换及介质分层与多金属导带处的边界条件,得到了关于其色散特性的计算方法,并给出了相应的曲线。为鳍线的设计和制造提供了有力依据。本文的分析方法,也适用于研究任何多层介质多金属导带的平面波导结构。

In this paper,the study of unilateral fin and bilateral fin with two- layer dielectric are done with the method of lines.By the analysis of the transforma- tion of electromagentic potential vector in the homogeneous region and in the dielec- lric interface and the multi-metallized strip boundary condition,the way calculating the dispersion characteristics of finIine structure with two-layer dielectric are obtain- ed.The results in this paper are very helpful to the design and manufacture of fin- line.The method of analysis can be used in the multi-layer dielectric and multi-me- tallized strips structure.
