Dual-band, double-negative, polarization-independent metamaterial for the visible spectrum

We present what is to our knowledge the first dual-band negative index metamaterial that operates in the visible spectrum. The optimized four-functional-layer metamaterial structure exhibits the first double-negative (i.e., simultaneously negative permittivity and permeability) band in the red regio...
