Negative Index Metamaterial for Two Distinct Polarizations: Double Negative at 813 nm and Single Negative at 770 nm

摘要

A negative index metamaterial demonstrating n=-1.0+0.8i with both negative effective permittivity and permeability at 813 nm of linearly polarized light is fabricated. It also exhibits a negative refractive index at 770 nm for orthogonal polarization.
