In the past few years, a new class of artificial metamaterials has been arisen, which possess both negative dielectric permittivity and negative magnetic permeability. Such materials were shown to have negative refraction index (n<0), thus leading to a number of exotic phenomena in microwave and optical ranges. In this report, a review is given on fundamental concepts and design features of the negative refractive index (“left-handed”) materials, starting from the pioneer theoretical work by V.G. Veselago [1] and remarkable practical ideas by J.B. Pendry and his co-workers [2]. Interplay with magnetic resonance is emphasized, including the use of FMR for producing negative permeability. Attention is given to physical grounds and experimental realizations of such striking effects as abnormal refraction, far-field imaging beyond the diffraction limit (“perfect lenses” and “hyperlenses”), the invisibility cloak, etc. Current state and further prospects in this field are discussed.
