摘　　要：微屏蔽线在使用过程中难免会产生变形。本文利用矢量有限元法讨论了矩形微屏蔽线和V形微屏蔽线的变形对其传输特性的影响,其中传输特性包括主模截止波长、单模带宽和主模电场结构。计算结果显示,两种微屏蔽线的变形对三种传输特性均有较大影响,这些数值计算结果对两种微屏蔽线在使用过程中出现变形时对整体器件的影响有较强的指导意义。Deformation of microshield lines is unavoidable during use.In this paper,the transmission characteristics in deformed rectangular-shaped and V-shaped microshield lines by edge-based finite element methods discussed.The transmission characteristics include the cutoff wavelength of dominant mode,single-mode bandwidth and the field patterns of dominant mode.The calculation results show that the deformation of the two kinds of microshield lines has a great influence on three transmission characteristics.These numerical results have strong guiding significance for the influence of deformation of the two kinds of microshielded lines on the overall device.
