The matrix methods for calculating of multilayer planar metamaterials characteristics in case of chirality and spatial dispersion

Application of matrix methods for calculating the characteristics of reflective metamaterials composed of several planar layers based on a media with spatial dispersion and chirality discussed in the work. The surface impedance and transmission matrices of generalized layer received. As an example, the problem of plane electromagnetic wave of linear polarization reflection from two-layer dielectric-chiral metamaterial basing on a thin wire coils located in the air and double-chiral metamaterial on a perfectly conducting substrate are considered. Frequency dependencies of reflection and transmission coefficients modules of the main and cross-polarized field components at the different container geometrical and the chiral metamaterial inclusions dimensions are considered. Metastructure enables the conversion of normally incident radiation in the scattering in the plane of the structure at some frequencies. Ability to use double-chiral metastructure a protective coating for the metallized object is predicted.
