Methods for solving incorrect tasks of electrodynamic analysis of radiating structures based on chiral metamaterials

Abstract

This article is devoted to the development of correct methods for electrodynamic analysis of single and multi-element radiating structures with substrates of chiral metamaterials. An approach to the electrodynamic analysis of such antennas based on the method of singular integral representations of the field and the method of surface impedances is proposed. A system of singular integral equations with respect to unknown distribution functions of current density over emitters is obtained. The proposed method was tested using the example of solving a test problem using the Feko software package. The prospects of using such ICs in MIMO systems are shown, which make it possible to increase their efficiency, in particular, to increase throughput. The effect of azimuthal scattering of electromagnetic waves is also presented, which can be used to create low-profile antennas of subscriber radio communication stations installed on mobile objects.
