ELECTROMAGNETIC-WAVES IN A CHIRAL PLASMA MEDIA

Electromagnetic waves in a magnetized chiral-plasma medium are studied . Using the Maxwell's equations and the proposed constitutive relation s for a chiral-plasma medium, we derive the vectors E and H equations and from these equations, dispersion relations and E-field polarizatio ns are founded. At high frequency, the obtained results for waves prop agating parallely to the external magnetic field in a cold magnetized chiro-plasma are compared with typical results obtained for a cold pla sma. For circularly polarized waves, a new mode conversion is founded due to the chiral effect. The chiral rotation is obtained and compared with the Faraday rotation. For waves propagating across the magnetic field, we found a shift of the cut-offs of ordinary and extraordinary waves, on the lower branch of the extraordinary wave mode there is no more bands of forbidden frequencies and the reflection point vanishes. At low frequency the effect of the chiral parameter on the fast and s low wave dispersion relations is moderate.
