    The subject of negative-index phenomena is drawing significant interest among researchers due to the emergence of a new class of artificially structured materials called metamaterials. Such materials can be engineered so that they have a much wider range of electromagnetic responses. Results reported to date demonstrate the negative refraction at microwave frequencies. Furthermore, recent experiments and theoretical work indicate that photonic crystals allow these effects to be demonstrated at visible wavelengths.
