Abstract

Negative refraction is currently achieved by driving the magnetic permeability and electrical permittivity simultaneously negative. It is studied an alternative route to negative refraction without manipulating these parameters ( εand μ) on a chiral magnetized plasma. By adding chirality to the plasma, we obtain windows where the refraction is negative. The size of these windows depends on parameters such as: chirality degree, external magnetic field and the angle of incidence of the electromagnetic wave. The present study demonstrates that the condition for negative phase-velocity propagation can be satisfied by non dissipative Faraday chiral medium such as a very dilute magnetized space plasma.
