Bi-gyrotropic impact upon high-performance transverse magneto-optical Kerr effect in a superlens

Abstract In this letter, we study the transverse magneto-optical Kerr effect (TMOKE) in a bi-gyrotropic superlens, and its dependence on the losses of both permittivity and permeability functions, which is a determining factor for the existence of the TMOKE. We found extreme values for this effect for both p- and s-polarized waves, and in particular the conditions under which these extreme values occur for a wide-range of the angle of incidence.
