摘要

折叠波导是一种很有前途的太赫兹行波管结构。本文利用CST Microwave Studio和Particle Studio对220GHz行波管的折叠波导慢波结构进行了设计和仿真。评估了相互作用阻抗和色散随频率的关系。讨论了增益与束流、电子发射角、能量扩散、磁通密度和输入功率等参数的关系。仿真结果表明，当波束电压为18KV，波束电流为10mA时，60周期折叠波导电路在220GHz时的增益为17.4dB。

Design and analysis of micro-machined folded waveguide slow-wave structure for 220 GHz application

Folded waveguide is a promising structure for THz travelling wave tube (TWT) application. In this paper, a folded waveguide slow-wave structure of 220GHz TWT is designed and simulated using CST Microwave Studio and Particle Studio. Interaction impedance and dispersion relation vs. frequency are evaluated. The relationship between gain and parameters such as beam current, electron's emitting angle, energy spread, magnetic flux density and input power, are discussed. Simulations of a 60 periods folded waveguide circuit show that the gain is 17.4dB at 220GHz when the beam voltage is 18KV and beam current is 10mA.
