摘要/Abstract

摘要： 提出用保角变换边界元组合法计算平行板-偏心圆柱耦合传输线的特性阻抗。通过对三种基本偏心结构的计算,获得平行板-偏心圆柱耦合传输线的特性阻抗数据。这些数据不仅可为平行板-偏心圆柱耦合传输线的准确设计提供理论依据,而且可为同轴传输线的加工制作精度提供理论参考。

Abstract: A new approach,conformal transformation combined with the boundary element method(BEM),is presented for computation of the characteristic impedance of coupled offset cylindrical bars transmission line between parallel plates.By this new method,the numerical results are obtained from three fundamental offset structures.These impedance data not only permit the exact design of various offset configurations of slab lines,but also provide a known accuracy for manufacturing various coaxial configurations of slab lines.

Key words: hybrid method, coupled offset cylindrical bars transmission line between parallel plates, characteristic impedance
