Abstract

In this paper, we report an planar Zero Index Metamaterial operating in the far-Infrared. The structure, consisting of a Ag screen surrounded by a polyimide substrate and superstrate, was optimized using a genetic algorithm to have a low/zero refractive index with maximum transmission. The measured properties of the fabricated sample show the excellent agreement with the simulations, achieving Re[neff] ≈ 0.41 and |T|2 ≈ −1.4 dB at 18.3 µm.
