THE Bi-Chirality Structure and Its Behaviour of Multilayered Uniaxial Chiral Composites

The generalized spectral domain-exponential matrix technique is used to study the reflection and transmission properties of multilayered uniaxial chiral composites which possess bi-chirality structures. Numerical results are presented to demonstrate the influences of the orientation axis,lossness, chirality and non-reciprocity parameters on the reflection and transmission coefficients. Especially ,the effect of cross-polarized transformation is considered. Our results suggest that bianisotropic uniaxial chiral materials have potential applications for the design of novel polarization transformers.
