介电常数e和磁导率n是决定电磁波在物质中传播的基本特征量。这是因为它们是出现在色散方程-kikj=0，(1)中的物质的唯一参数，它给出了单色波的频率Oj与其波矢量k之间的关系。对于各向同性物质，公式(1)具有更简单的形式：
J. HE dielectric constant e and the magnetic permeability n are the fundamental characteristic quantities which determine the propagation of electromagnetic waves in matter. This is due to the fact that they are the only parameters of the substance that appear in the dispersion equation-kikj= 0,(1) which gives the connection between the frequency OJ of a monochromatic wave and its wave vector k. In the case of an isotropic substance, Eq.(1) takes a simpler form:
