Characteristics of the gyrotropic-nihility state are studied in a finely-stratified ferrite-semiconductor structure, which is under an action of an external static magnetic field. Investigations are carried out with the assistance of the effective medium theory, according to which the studied structure is approximated as a uniform gyroelectromagnetic medium. The theory of the gyrotropic-nihility state is developed in terms of the eigenwaves propagation in such gyroelectromagnetic medium. The…

TLDR
It is shown that the TM modes in a gyromagnetic photonic crystal can be formally mapped to electronic wave functions in a periodic electromagnetic field, so that the only requirement for the existence of one-way edge modes is that the Chern number for all bands below a gap is nonzero.
