Results of theoretical and experimental investigations of artificial metamaterials based on composite of straight and circular conductors for radio wave range are presented. It is demonstrated that for small conductor sizes, nonresonant character of metamaterial properties of the artificial medium is retained. The possibility of application of metamaterials for increasing resolution in radio tomography...
