摘　　要：对突变两侧加载损耗介质的场匹配进行了解析分析 ,导出加载损耗介质圆柱波导半径突变两侧场展开系数的复线性方程组 .数值求解该方程组 ,得到入射波在突变两侧产生的反射波及其它模式的场 ,研究加载损耗介质的突变低Q圆柱谐振腔 .本文的理论分析及数值计算直接应用于回旋速调放大器高频系统设计和分析 .The theoretical analysis of abrupt structure loaded with lossy material on both sides has been described. Dispersion equations of waveguides and field matching equations of hybrid modes (HEM) for abrupt structures with absorber are derived. Further, numerical solution of the equations is used to analyze the field of different modes in each region and study the properties of waveguides and abrupt cavities loaded with lossy material. The theoretical analysis and calculation code are used to design and study the low Q cavities for gyroklystrons.
