摘要
迴旋自谐振脉塞是一种工作在毫米、亚毫米波段、兆瓦级以上功率的相干辐射器.本文叙述了迴旋自谐振脉塞的基本原理,着重给出谐振系统——Bragg腔的分析设计方法和计算结果.从皱纹波导理论出发,根据它的分布反射特性,推导出一个相关参数S.利用S参数结合实例可以较为简捷地设计、选择Bragg腔的工作模式.
The cyclotron autoresonance maser (CARM) has been developed which is a high power device operating at short wavelength. In this paper, the basic principle of CARM is described, and the design method and numerical calculation results for Bragg cavity are shown. Based on the distributed reflection performance of the corrugated waveguide, an important parameters S is found with application of coupled-wave theory. S parameter is used simply to design a Bragg cavity and to select one of the operation modes. Finally some discissions are made.
