基于圆柱谐振腔的高功率微波脉冲压缩系统
High power microwave pulse compression system based on cylindrical resonant cavity
摘要
Abstract
High power microwave ( HPM ) pulse compression is a main method to obtain high power microwave with nonrelativistic devices. The mature HPM pulse compression systems are nearly all based on rectangular resonant cavity, and the pulse compression systems based on cylindrical resonant cavity are in progress. A new type pulse compression system based on cylindrical resonant cavity is proposed in this paper, and the structure of the system is different from those of all other HPM pulse compression systems ever reported. The structure and the numerical simulation results of the key parts are presented, and a preliminary analysis of the power capability of the system and the quality factor of the resonant cavity is also given. For a pulse compression system, the power capacity is a key factor for the output microwave pulse power,and the quality factor of the resonant cavity has a close relationship with the system energy efficiency. According to the experimental results,the pulse capacity of the pulse compression system based on cylindrical resonant cavity can be 10 times higher than that of the systems based on the rectangular resonant cavity, and the quality factor of the resonant cavity can be improved by a factor of 5.关键词
