Abstract

In this paper, we present a free-standing optical zero-index metamaterial (ZIM) with a symmetric structure in the direction of wave propagation. The metamaterial consists of a gold-polyimide-gold tri-layer stack perforated by air holes to form a fishnet geometry. With the aid of a genetic algorithm (GA), this structure is optimized to exhibit a near-zero refractive index with low absorption loss and a good impedance match to free space. The ZIM was fabricated and characterized. The measured results are found to be in strong agreement with the simulation predictions.
