Paper Abstract

Since the event of metamaterials, a considerable effort has been performed to fabricate them in the infrared and optical regimes. However, apart from the experimental demonstration and observation of H. J. Lezec et al based on surface plasma polariton, direct visualisation of negative refraction based on metal-dielectric resonances have not been performed experimentally so far in the infrared or visible regime (photonic crystals with periodicity on the order of the wavelength are not considered here). Very often only simulations have given the needed phase information for the retrieval methods in optical experiments. In this paper, a metamaterial composed of SRR (Split Ring Resonators) and a continuous wire is considered. We extract the phase information from the transmission and the reflection measurements through a diffraction grating made of the metamaterial to be characterized and silicon or gold. This retrieval allows a unambiguous retrieval of the effective parameters under conditions discussed in the paper at IR and visible wavelengths.
