✦ Synopsis

Based on Maxwell's equations and Ohm's law, we rederived the Snell laws for reflection and transmission of harmonic inhomogeneous plane electromagnetic (EM) waves propagating through planar lossy interfaces. The present results are new, simple and exact and they recover the ordinary Snell laws in the case of lossless media. Besides, these results show that the wave propagation direction strongly depends on the polarization state of the EM wave and the lossy media can behave as a polarizing device. Moreover, we verify that in low frequency regime these traveling waves do not exhibit total internal reflection at interfaces between two adjacent lossy media.

## Abstract Cabeceira et al. recently presented a time‐domain analysis of wave propagation in a Tellegen medium [1]. Their analysis is ill‐founded because (i) the existence of any Tellegen medium is not tenable within modern electromagnetic theory; and (ii) the constitutive relations employed are n
