【摘要】：基于三级级联模式,通过在漂移段采用切断方式、在预群聚段和辐射段采用光子晶体加载所需模式,利用CST对太赫兹波段光子晶体曲折波导慢波结构的高频特性作了模拟计算。计算结果表明:在f=225 GHz处,光子晶体加载曲折波导慢波结构有较平缓的色散关系,耦合阻抗为3.7Ω;当工作电压为13 kV、电流为56 mA、电子注半径为0.09 mm时,慢波结构在输入功率为5 mW情况下在f=225 GHz处具有30.4 d B的增益;与相同条件下的普通曲折波导慢波结构相比,频带显著变宽,输出功率增大1.4倍。
[Abstract]:Based on the three-stage cascade mode, the high frequency characteristics of the zigzag waveguide slow wave structure in terahertz band are simulated by CST by using the mode of cutting off in the drift section and the mode of photonic crystal loading in the pre-cluster segment and the radiation section. The results show that the slow wave structure of photonic crystal loaded zigzag waveguide has a gentle dispersion relation at f 鈮，
