中文摘要:
      研究了G波段双注折叠波导(FWG)TE20模的基本特性。首先计算了双注FWG TE20模的高频特性,采用等效电路法计算了色散特性;根据定义式计算了耦合阻抗,同时将二者的计算结果与HFSS仿真结果进行对比。结果显示,色散特性随频率升高差距增大,耦合阻抗随频率升高差距降低。利用电磁仿真技术(CST)粒子模拟软件对双注FWG TE20模的注-波互作用情况进行仿真,得到了慢波结构中电子轨迹以及输入输出信号频谱图,结果表明,在工作频率为205 GHz时,四段FWG的增益为34.74 dB。
英文摘要:
      The basic characteristics of the G-band two-beam Folded Waveguide(FWG) TE20 mode are investigated. Firstly, the high frequency characteristics of two-beam FWG TE20 mode are calculated. The dispersion characteristic is calculated by the equivalent circuit method. The coupling impedance is calculated according to the definition. The results are compared with the HFSS simulation results. The results show that the dispersion characteristics differ more greatly as the frequency increases, and the coupling impedance decreases as the frequency increases. Then, the Computer Simulation Technology(CST) particle simulation software is utilized to simulate the beam-wave interaction of the FWG, the electron trajectory and the input and output signal spectrum in the slow wave structure are obtained. The results show that at the operating frequency of 205 GHz, the gain of four-part FWG is 34.74 dB.
