摘要

介绍了一种在太赫兹波段提高折叠波导行波管波束相互作用效率的有效方法。为了提高电子效率，对高频电路进行了优化，采用变周期技术对动态变周期FWG行波管进行了优化设计，并利用三维电磁场软件微波管仿真软件(MTSS)进行了粒子仿真。仿真结果表明，动态变周期FWG行波管在214 GHz ~ 223 GHz频率范围内输出功率大于78 W，电子效率大于7.2%。与均匀周期结构相比，动态变周期结构的饱和输出功率从55.06 W提高到86.41W, 220 GHz的最大电子效率从4.987%提高到7.94%。

Design and Study of High Efficiency Folded Waveguide Slow Wave System

This paper introduces an effective method to improve the beam-wave interaction efficiency of folded waveguide Travelling-Wave Tube in terahertz band. In order to improve the electron efficiency, the high frequency circuits are optimized and the variable period technology is used to optimize the design of dynamic variable period FWG TWT, and the particle simulation is performed using the three-dimensional electromagnetic field software Microwave Tube Simulation Software (MTSS). The simulation results show that the output power of dynamic variable period FWG TWT is over 78 W in 214 GHz - 223 GHz frequency range and the electron efficiency is greater than 7.2 %. Compared with uniform periodic structure, the saturated output power of dynamic variable period structure increases from 55.06 W to 86.41W, the maximum electron efficiency raises from 4.987 % to 7.94 % in 220 GHz.
