摘　　要：随着频率的增加,行波管尺寸变得越发小巧,从而给加工带来更大的困难。相比于圆形电子注,带状电子束横向尺寸较小,空间电荷效益较低,效率较高,是一种比较理想的辐射源。于是,基于微细加工技术(MEMS)且能与带状电子注互作用的新型行波管慢波结构成为了重要发展趋势。本文正是由此思路,在圆横截面慢波结构研究基础上,提出了一种新型慢波结构,即矩形环中心杆慢波结构,并通过实验仿真对这种新型结构的高频特性进行了的研究。As the frequency increases,the size of the traveling wave tube becomes small,which brings greater difficulties to processing.Compared with the circular electron beam,the sheet electron beam has a smaller lateral size,lower space charge force,and higher efficiency,making it an ideal radiation source.Therefore,a new type of traveling wave tube slow-wave structure based on the micro-electro-mechanical systems(MEMS)and capable of interacting with sheet electron beams has become one of the significant development trends.According to this idea,based upon the circular cross-section slow-wave structure research,a novel type of slow wave structure is presented,that is,a rectangular single-bar slow-wave structure.The high-frequency characteristics of this new structure are studied through experimental simulation.
