摘 要
在本研究當中,第二章到第四章是利用朱國瑞教授所發展出的磁旋行波放大器非線性理論及模擬程式,探討迴旋電子與電磁波間能量傳遞現象,計算電磁波放大結果。而能量傳遞過程中,電子群聚效應扮演著重要的角色,為了更瞭解群聚現象產生的過程及群聚電子與電磁波極化相位間關係,新定義B1、B2兩種指標方便觀察群聚現象隨著位置如何變化,進而將複雜的非線性現象作有物理意義的解釋,幫助我們更瞭解磁旋行波放大器的特性,利用群聚指標的瞭解,於第四章發展出傾斜作用段結構,在模擬中有效提昇放大效率,並大大增加高效率區頻寬。也為未來優化留下很大的空間。第五章為利用HFSS模擬程式,設計高純度圓形波導TE21模耦合器,為發展中的高次模磁旋行波放大器提供了更有利的條
