摘要: 迴旋自諧振脈塞是一種工作在毫米、亞毫米波段、兆瓦級(jí)以上功率的相干輻射器.本文敘述了迴旋自諧振脈塞的基本原理,著重給出諧振系統(tǒng)Bragg腔的分析設(shè)計(jì)方法和計(jì)算結(jié)果.從皺紋波導(dǎo)理論出發(fā),根據(jù)它的分布反射特性,推導(dǎo)出一個(gè)相關(guān)參數(shù)S.利用S參數(shù)結(jié)合實(shí)例可以較為簡(jiǎn)捷地設(shè)計(jì)、選擇Bragg腔的工作模式.

Abstract: 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 discussions are made. -
