Comments on arXiv:1006.0972 “XENON10/100 dark matter constraints in comparison with CoGeNT and DAMA: examining the Leff dependence”

Kavli Affiliate: Juan I. Collar | First 5 Authors: J. I. Collar, , , , | Summary: Savage et al. have recently put forward the claim that results from the XENON10 experiment are incompatible with the totality of both DAMA/LIBRA and CoGeNT experimental regions. In this brief note the source of this erroneous conclusion is […]

Three-dimensional negative index of refraction at optical frequencies by coupling plasmonic waveguides

Kavli Affiliate: Kobus Kuipers | First 5 Authors: Ewold Verhagen, RenĂ© de Waele, L., Kuipers, Albert Polman | Summary: We identify a route towards achieving a negative index of refraction at optical frequencies based on coupling between plasmonic waveguides that support backwards waves. We show how modal symmetry can be exploited in metal-dielectric waveguide pairs […]
