宽带行波管螺旋线慢波结构耦合阻抗的计算

Computing of Interaction Impedance for Helix Slow Wave Structure in Broadband TWTs

金属翼片加载螺旋线电路是多倍频程行波管中广泛应用的慢波结构。本文对这种宽频带慢波结构的重要参量──耦合用抗进行了计算，在很宽的频率范围内，理论计算结果与发表的实验值相当吻合。

A metal vane-loaded helix circuit has been widely used in slow wave structurefor multi-octave-band traveling wave tubes.Interaction impedance,an important parameter ofthe broadband slow wave structure,is calculated in this paper.Theoretical values agree closelywith published experimental results over a wide range of frequencies.
