波导波导waveguide用来约束或引导电磁波的结构。通常,波导专指各种形状的空心金属波导管和表面波波导,前者将被传输的电磁波完全限制在金属管内,又称封闭波导;后者将引导的电磁波约束在波导结构的周围,又称开波导。当无线电波频率提高到3000兆赫至300吉赫的厘米波波段和毫米波波段时,同轴线的使用受到限制而采用金属波导管或其他导波装置。波导管的优点是导体损耗和介质损耗小;功率容量大;没有辐射损耗;结构简单,易于制造。波导管内的电磁场可由麦克斯韦方程组结合波导的边界条件求解,与普通传输线不同,波导管里不能传输TEM模,电磁波在传播中存在严重的色散现象,色散现象说明电磁波的传播速度与频率有关。表面波波导的特征是在边界外有电磁场存在。其传播模式为表面波。在毫米波与亚毫米波波段,因金属波导管的尺寸太小而使损耗加大和制造困难。这时使用表面波波导,除具有良好传输性外,主要优点是结构简单,制作容易,可具有集成电路需要的平面结构。表面波波导的主要形式有:介质线、介质镜像线、H-波导和镜像凹波导。
