什么是驻波比？它的正常数值是多少 驻波比全称为电压驻波比，又名VSWR和SWR，为英文Voltage Standing Wave Ratio的简写。波传递从甲介质传导到乙介质，会由于介质不同，波的能量会有一部分被反射这种被反射的波。

已知驻波比（VSWR），如何计算反射波功率所占百分比？已知驻波比（VSWR），如何计算：反射波功率/（发射功率+反射功率）？令：发射功率+反射功率=100%不要dB形式表示，要。
传输线驻波状态时的驻波比和反射系数是多少？ 传输线驻波状态时的驻波比和反射系数是1，0.反射系数、驻波比、S参数之间的关系回波损耗(Return Loss)：入射功率/反射功率，为dB数值反射系数(Г)：反射电压/入射电压，为标量。
反射系数，驻波比和行波系数反映负载与传输线的什么关系 驻波电压的波腹（最大值）Umax与波节（最小值）Umin之比被定义为驻波比，记作SWR。对无损耗传输线来说，驻波比与电压终端反射系数具有下列关系：式中Γ称为电压终端反射。
