Title: The effect of chirality on a plasma media
Author: TorresSilva, H

Abstract: 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 nonreciprocity based upon the constitutive relationships between electromagnetic vectors (E) over right arrow, (B) over right arrow, (H) over right arrow, (D) over right arrow. Using the Maxwell's equations and the proposed constitutive relations for a chiral-plasma medium, we derive the vectors (E) over right arrow and (H) over right arrow equations and from these equations, dispersion relations and (E) over right arrow-field polarization are obtained. For circularly polarized waves, a new mode conversion is founded due to the chiral effect. For the lower branch of the extraordinary wave mode there is no more bands of forbidden frequencies and the reflection point vanishes when the chiral parameter increases.
