摘要

電子迴旋脈射是一種能夠產生高頻、高功率輻射的電磁輻射機制。基本上，它利用迴旋運動中相對論性電子去激發電磁輻射。共振結構裡的RF電磁波會與相對論性電子作用，進而將電子動能轉為電磁波能量。一般來說，共振結構可能以開口式共振腔、開口式波導或者是複雜周期結構等形式存在。本文旨在分析理想共振腔裡的電子迴旋脈射物理現象。

The electron cyclotron maser (ECM) is a mechanism of electromagnetic radiation which is used to produce high-power and broad-band electromagnetic waves. It's a mechanism based on a stimulated cyclotron emission process involving relativistic electrons in a gyrational
motion. The fi elds in the RF structure are used to extract energy from the relativitistic electrons in order to enhance their own intensity. Generally speaking, the RF structure may exist in the form of a resonant open cavity, a open-end waveguide, or a complex periodic structure. The main purpose of this thesis is to discuss, in view of physics, the phenomena produced by electron cyclotron maser in an ideal cavity.
