By a large amount of calculations, the influence of the structure dimensions and the dielectric parameters on dispersion characteristic and coupling impedance of this kind of slow - wave structure is obtained. then, the linear beam - wave interaction theories of the arbitrarily - shaped helical groove waveguide and the dielectric into the arbitrarily - shaped helical groove waveguide are deduced. by the numerical calculations, the relationship is got between the small signal gain, bandwidth, electromagnetic " hot " velocity and the electronic beam, the structural parameters
通過數值計算，獲得了此類慢波結構的色散特性和耦合阻抗隨結構幾何尺寸和介質參數的變化規律;在此基礎上，建立了任意槽形螺旋槽及中心加介質棒的任意槽形螺旋槽行波管的注-波互作用線性理論，並編製程序，計算了管子的小信號增益、帶寬、電磁慢波的「熱」相速與電子注參數、結構參數之間的關系，獲得了增加帶寬或增益的途徑。In this paper a newly develoed helical coordinates is used to make out the solution of electromagnetic fields in the helix gap and calculate dispersion characteristics of tape helix slow wave structure for the first time. strict boundary conditions for magnetic fields are adopted and are treated rigorously by fourier expansion. besides, the radial propagation constant of every layer in the dielectric - loaded region is differentiated. some of practical tape helix slow wave structures have been calculated for dispersion characteristics and the calculated values accord with measured values very well. the authors also compare the calculated results with experiments for different structures by changing tape thickness or other structure parameters and find that the theory in the paper is universal
本文首次運用螺旋坐標系給出了帶狀螺旋線縫隙內的電磁場解，並據此計算了帶狀螺旋慢波結構的色散特性.文中採用了嚴格的邊界條件，並以傅立葉展開進行了嚴格的數學處理.另外還首次對有介質區域內各層的徑向傳輸系數作了區別.本文使用這種方法計算了我們已研製的一些寬帶高功率行波管所用的慢波線結構的色散特性，理論與實驗符合得很好.我們還計算了不同結構參數對色散特性的影響，並與實驗作了對照，發現本文的理論有一定的普適性
