We dispute Grigorenko’s statement [ Opt. Lett. 31, 2483 (2006) ] that measuring only the reflection intensity spectrum is sufficient for determining the effective refractive index. In addition, our simulations do not confirm his conclusions regarding the negative refractive index and the negative permeability of the nanopillar sample in the visible range.
