摘要： 分析了W波段折叠波导慢波系统的尺寸对其冷特性的影响,并利用电磁场分析软件MAFIA计算了不同金属材料折叠波导慢波系统在W频段下的功率损耗值.结果表明,影响其色散特性的主要几何参数是结构的几何周期和波导宽边值;影响耦合阻抗的主要几何参数是波导窄边值;影响功率损耗的主要因素是金属的电导率以及波导窄边值.
关键词: 慢波系统, 色散, 耦合阻抗, 功率损耗
Abstract: Influence of the dimensions of W-band folded waveguide slow-wave system on its cold characteristics was investigated, and the power loss of different folded waveguides made of different metal materials was calculated in Wband using the electromagnetic software MAFIA. The calculated results show that the main geometric parameters affecting the dispersion are the geometric period and the value of waveguide broad side; the main geometric parameter influencing the coupling impedance is the value of waveguide narrow side;and the main geometric parameters controlling the power loss are the metal’s conductivity and the value of waveguide narrow side.
Key words: slow wave system, dispersion, coupling impedance, power loss
