摘要
大功率和宽频带是太赫兹放大器追求的两个核心指标,基于交错栅慢波结构的带状注行波管兼具两者,是一种非常有竞争力的太赫兹放大器.研究交错栅慢波结构的色散特性、耦合阻抗特性、传输反射特性以及注波互作用特性,通过优化结构参数以及引入介质衰减器,实现该管宽频带内的大功率稳定输出.仿真结果表明,该管在220～260 GHz的输出功率可达105 W以上.所做工作为研究宽频带和大功率太赫兹放大管奠定良好基础.
High power and broad bandwidth are two core targets for a terahertz amplifier. A sheet beam travelling wave tube based on a staggered double vane slow wave structure possesses the two advantages mentioned above and is a very competitive high power terahertz amplifier. The dispersion characteristic,coupling impedance property,transmission and reflection properties and beam wave interaction property are investigated. The tube achieves high output power in a very broad frequency range by optimizing the structural parameters and introducing a dielectric attenuator.Simulation results show that the tube can generate the output power of more than 105 W in the frequency range from220 GHz to 260 GHz. This work has laid a good foundation for the study of terahertz amplifiers with broad bandwidth and high power.
