Abstract

Methods for calculating the electrodynamic characteristics of single and multi-layered planar chiral metamaterials based on fine-wired ideally conducting helices placed in a dielectric container are considered in this paper. The effective dielectric constant of the chiral metamaterial is determined on the basis of the Maxwell - Garnett relations. In this paper the dispersion dependences of the material parameters for the considered metamaterial are obtained. The problems of the plane electromagnetic waves reflection from metastructures based on one and two planar layers of the chiral metamaterial have been solved. The possibility of incident microwave energy discrete multi-frequency concentration at a number of resonant frequencies is proved. The matrix theory for describing a multilayer chiral metamaterial and the obtained relations for the transfer matrices of the chiral layer based on helices are considered. It is proved that a two-layer chiral-dielectric metamaterial based on thin-wire conducting helices near a predetermined frequency allows frequency-selective conversion of a normally incident flux of electromagnetic energy into azimuthal scattering in the plane of the metastructure.
