Artificially engineered metamaterials are now demonstrating unprecedented electromagnetic properties that cannot be obtained with naturally occurring materials. In particular, they provide a route to creating materials that possess a negative refractive index and offer exciting new prospects for manipulating light. This review describes the recent progress made in creating nanostructured metamaterials with a negative index at optical wavelengths, and discusses some of the devices that could…

Comment on "Negative refractive index in artificial metamaterials".
TLDR
This paper disputes Grigorenko's statement that measuring only the reflection intensity spectrum is sufficient for determining the effective refractive index and simulations do not confirm his conclusions regarding the negative refractiveIndex and the negative permeability of the nanopillar sample in the visible range.
