Abstract
Azzam recently described [ Opt. Commun. 41, 223 ( 1982)] an optical 0 ↔ 1 switching device for two media in which the incident light is totally reflected in one orientation while there is no reflection (for the parallel polarization at Brewster’s angle) in the other orientation. He showed that this phenomenon could exist only when the incidence angle is 51.8° and the ratio of refractive indices is 1.272. Here we show that, for the generalized case when magnetic media are considered, the same phenomenon can occur for any angle of incidence and either polarization, provided that the proper media permittivity and permeability ratios are chosen.
