Electromagnetic nonreciprocity and gyrotropy of graphene
Abstract
The authors study the transmission properties of magnetically biased graphene via the general anisotropic conductivity tensor, which accounts for both the diagonal and the Hall conductivities. Appreciable gyrotropic and electromagnetic nonreciprocal (time reversal asymmetry) properties are observed at subterahertz frequencies, which result in an extremely broadband nonreciprocal polarization rotation phenomenon.
