The structure consists of stacked bilayers of metal cutwire and wire pairs, which are separated by a thin dielectric layer. The existence of the negative index of refraction is inferred from the transmission and phase spectra obtained by using multilayer metamaterial samples. Another metamaterial structure incorporating non-magnetic (electrically shorted) cutwire pairs does not exhibit the corresponding transmission band, which supports the true lefthanded behavior of the metamaterial. © 2006 Optical Society of America.EnglishDielectric materialsElectric wireMagnetic propertiesMicrowavesWave propagationMetamaterial structureMultilayer metamaterialsPhase spectraTransmission bandsLight transmissionArticle10.1364/OE.14.008685
