慢波系统是真空电子器件进行注-波互作用激发微波能量的核心,它的性能优劣直接影响了真空电子器件的技术水平,为了解决太赫兹波段所面临的频带窄、互作用效率低等问题,本文将太赫兹波段光子晶体矩形栅慢波结构的耦合阻抗和色散特性,与传统矩形栅慢波结构的相关参数进行了对比,并分析了太赫兹波段光子晶体矩形栅慢波结构的晶格常数、光子晶体柱半径、光子晶体柱与矩形栅之间的距离等结构参数对于“冷参数”的影响。结果表明:具有光子晶体的慢波结构,带宽更宽、色散更弱、耦合阻抗更大;调整结构参数后的数据为光子晶体矩形栅慢波系统的结构设计和参数优化提供了良好的依据。
The slow wave system is the core of the vacuum electron device that injects and injects waves into the microwave energy. The performance of the vacuum wave device directly affects the technical level of the vacuum electronic device. In order to solve the narrow band and low interaction efficiency of the terahertz band In this paper, the coupling impedance and dispersion characteristics of the rectangular grid slow-wave structure in the terahertz band are compared with the related parameters of the conventional rectangular grid slow-wave structure, and the crystal of the slow-wave structure of the rectangular grid in the terahertz band Lattice constants, photonic crystal column radius, photonic crystal column and the distance between the rectangular grid structure parameters such as “cold parameters ”. The results show that the slow-wave structure with photonic crystal has wider bandwidth, weaker dispersion and larger coupling resistance. The data after adjusting the structure parameters provide a good basis for the structural design and parameter optimization of the photonic crystal rectangular grid slow-wave system.
