| Summary: | Title screen We propose and demonstrate a type of composite metamaterials, which is constructed by combining thin copper wires and split ring resonators on the same board. Using the optimized target parameters we had investigated the orientation-angular dependence of radiation refraction in metamaterial target. The measurements were performed in free space as well, as the spectral characteristics of refracted radiation in comparison with the initial spectra. The measured dependences show the formal correspondence of the radiation characteristics to the negative refraction index of the metamaterial structures. This correspondence is only formal one, which follows from the Snellius law, because really the permittivity and the permeability should be considered as macroscopic tensor characteristics of metamaterial Режим доступа: по договору с организацией-держателем ресурса |
