Rotatory power reversal induced by magnetic current in bi-isotropic media

Bi-isotropic media constitute a proper scenario for scrutinizing optical effects stemming from magnetoelectric parameters. Chiral magnetic current is macroscopic effect arising the chiral that enriches phenomenology of classical dielectric medium. This paper examines aspects bi-isotropic in presence Ohmic and conductivity. The full isotropic manifests circular birefringence described by dispersive rotatory power changes sign at given frequency. For medium with antisymmetric conductivity, an intricate attained, supplied reversal as well. occurs absence or It also indicates handedness reversion medium, unusual property dielectrics, which may work signature supporting current.
