摘要
针对波纹圆波导,在考虑均匀圆柱区的空间谐波和矩形皱纹槽区的高阶模的情况下,利用模匹配法得到了传输HE模时频散方程的解析表达式,并且对角向均匀的TM模式进行了重点分析,给出了其频散特性,分析了结构参数的变化对通带、禁带特性的影响以及TM01模的衰减特性,同时进行了验证,本文的工作对微波工程应用有着重要的价值。
Considering space harmonics in the interior and higher order modes in the slot region of the rectangular corrugated cylindrical waveguide, the dispersive equation of HE modes is derived by using the mode matching method. The uniform modes in angular direction are particularly analyzed. The dispersion and attenuation characteristics as well as the influence of passband and stopband properties with the changes of structural parameters are given. The conclusions of this paper are verified. The work of this paper is valuable to microwave engineering application.
