Electromagnetic properties of a chiral-plasma medium

The theoretical properties of a composite chiral-plasma medium are developed. By using the reaction theorem for a magnetized chiroplasma, we obtain the proof of non reciprocity based upon the constitutive relationships between electromagnetic vectors E, B, H, D. Using the Maxwell's equations and the proposed constitutive relations for a chiral-plasma medium, we derive the vectors E and H and from these equations, dispersion relations and E-field polarizations are based. The obtained results for waves propagating parallel to the external magnetic field in a cold magnetized chiroplasma are compared with typical results obtained for a cold plasma. For circulary polarized waves, a new mode conversion is founded with the chiral effect. The chiral rotation is obtained and compared with 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 bands of forbidden frequencies and the reflection point vanishes when the chiral parameter increases. (author)
