An overview of the problems involved in the study of electromagnetic power transmission between lossy media is presented. Starting from the well-known problem of the transmission at a dielectric-conductor interface, the different representations of the complex propagation vector of the plane waves are introduced. Analytical expressions to convert from one formulation to the other are obtained. Moreover, the transmission of a plane wave at the interface between two lossy media is taken into account. An explanation of the strange behavior of the transmitted wave is developed by means of power considerations. Finally, the interesting effect of the parallel-attenuated transmitted wave is presented, and its properties as a function of the incident phase vector amplitude are deduced.
本文概述了有损介质间电磁功率传输研究中涉及的问题。从电介质 - 导体界面处传输的著名问题出发，介绍了平面波复传播矢量的不同表示形式。得到了从一种表述形式转换为另一种表述形式的解析表达式。此外，还考虑了平面波在两种有损介质界面处的传输。通过功率考量对透射波的奇异行为进行了解释。最后，给出了平行衰减透射波的有趣效应，并推导了其作为入射相位矢量幅度函数的性质。
