Abstract:

Received February 28, 2006; revised April 3, 2006; accepted April 3, 2006; posted April 5, 2006 (Doc. ID 68552) We fabricate and characterize a low-loss silver-based negative-index metamaterial based on the design of a recent theoretical proposal. Comparing the measured transmittance and reflectance spectra with theory reveals good agreement. We retrieve a real part of the refractive index of Ren=-2 around 1.5 m wavelength. The maximum of the ratio of the real to the imaginary part of the refractive index is about three at a spectral position where Ren=-1. To the best of our knowledge, this is the best figure of merit reported for any negative-index photonic metamaterial to date.
