摘要
论述了电磁波在导电介质内的传播方向、与电场有关的能量、穿透深度以及良导体内电磁波的相速等问题,讨论了电磁波在导电介质中传播时,σc/ωε对导电介质电性能的影响.对于良导体和不良导体,分别给出了电磁波穿透深度的计算方法.研究结果对如何根据电磁波的频率来处理导电介质的电性能问题具有一定的理论研究和实际应用意义.
The propagation direction, the energy relative to electric field, the penetration depth, and the phase velocity et al of the electromagnetic wave in conductive medium, and the influence of σc/ωε on the electric quality of conductive medium were discussed. For the good and poor conductor, the method of calculating the penetration depth of the electromagnetic wave was presented. This discussion has some theoretical research and practical appfication significance for how to treat the electric quality of conductive medium according to the frequency of the electromagnetic wave.
