In this work creation of structure from ring conductors having negative index of refraction is shown. Experimental confirmation and finding of index of refraction, namely its real and imaginary part taking into account the error, for single-layer, two-layer, three-layered and four-layer structure.

In this work are presented, results of computer model operation of the structure executed from triangular elements with openings in the center. Results of mathematical calculation of amplitude and phase distribution of an electric field with use of CST Microwave studio are given. Also, calculation of the equivalent index of refraction when passing a plane wave through this structure is given.

This article presents the results of numerical and computer modeling of the flat closed conductor with different variants of arrangement. The interaction of the conductors is examined and the results of active and reactive part of the Poynting vector for each structure is presented. According to the results the model with identical parameters for each element was built and examined for the presence of metamaterial properties.
