The incidence of an inhomogeneous plane wave on the interface between two lossy media is analyzed. The analytical expressions of the incidence angle of the phase vector, for which the transmitted wave has the phase or the attenuation vector parallel to the interface, are obtained. The transmitted wave with the attenuation vector parallel to the interface is physically interpreted, finding a wave in a lossy medium without attenuation away from the interface. The same effect appears at the interface between a lossless medium and a lossy one.
分析了非均匀平面波在两种有耗介质界面上的入射情况。得到了透射波的相位矢量的入射角的解析表达式，其中透射波的相位或衰减矢量与界面平行。对与界面平行的衰减矢量的透射波进行了物理解释，发现了一种在远离界面的有耗介质中没有衰减的波。在无耗介质与有耗介质的界面上也会出现同样的现象。
