Abstract

The idea of a substance with simultaneously negative values of dielectric permittivity ε and magnetic permeability μ presented by Veselago in 1968 has been brought to reality. Firstly, negative permittivity ε(ω) of a three dimensional photonic structure composed of thin metal wires was experimentally demonstrated in the GHz range. Secondly, a concept of split ring resonator has appeared and a structure composed of such metal resonators was shown to have negative permeability μ. Consequently, in a so called double negative, both ε(ω) and μ(ω) < 0, composite material made of cells consisting of a split ring resonator and a wire unnatural phenomenon of negative refraction was experimentally observed in the microwave spectral region. Recently, perfect lenses made of metamaterial with negative refraction index, photonic crystal or metal slabs were used to focus light below the diffraction limit of resolution. Electromagnetic transport of energy in plasmon waveguides made of subwavelength metallic elements offers a great potential value for nanoscale photonic devices of the future.
