摘　　要：运用矢量有限元法对填充右左手材料的矩形屏蔽微带线的色散特性进行比较研究,包括矩形单信号对称屏蔽微带线,矩形单信号不对称屏蔽微带线,矩形双信号对称屏蔽微带线,矩形双信号位置不对称屏蔽微带线,矩形双信号宽度不对称屏蔽微带线以及矩形双信号厚度不对称屏蔽微带线六种情况.讨论这些屏蔽微带线的主模色散特性随填充材料的变化,色散特性的研究有助于矩形屏蔽微带线和左手材料在新型微波器件中的应用.Edge-based finite element method is introduced to study dispersions of six types of rectangle-shaped microshield lines loaded with right-handed materials and left-handed materials. They are rectangle-shaped microshield lines with symmetrical single signal line,with asymmetrical single signal line,with symmetrical dual signal lines,with asymmetrical dual signal lines of position,with asymmetrical dual signal lines of width and with asymmetrical dual signal lines of height. Dispersions of microshield lines with changed dielectric constant of dielectric substrate are discussed. Numerical results are helpful in design of microwave components that use rectangle-shaped microshield lines and left-handed materials.
