摘要：Scientific Reports 2 , Article number: 0583 10.1038/srep00583 ( 2012 ); Published: 16 August 2012 ; Updated: 28 February 2014 This Article contains a typographical error in an equation in the Methods section: “ε 1 = μ 1 = 1 − ω 2 /(ω p 2 + iωΓ)” should read “ε 1 = μ 1 = 1 − ω p 2 /(ω 2 + iωΓ)”. In addition, the two thin red arrows representing the direction of the wave vector should be reversed in Figure 2a.
