Alloy-based wire array metamaterial fibers and hyperlenses for imaging applications at MIR frequencies
We propose and demonstrate the fabrication of wire array metamaterial fibers and hyperlenses based on Ag72Cu28 wires embedded in borosilicate glass for imaging applications at mid-infrared frequencies. Initial numerical modeling indicates smaller optical losses for such a system in comparison to the equivalent Sn/soda-lime structures reported recently in the literature. Modeling of the proposed and fabricated magnifying hyperlenses shows promising overall optical losses between 11 dB to 16 dB (depending on the structural parameters) when operating at 5 μm wavelength. Their experimental characterization and the proof-of-concept far-field sub diffraction imaging experiment are in progress.

Abstract
We propose and demonstrate the fabrication of wire array metamaterial fibers and hyperlenses based on Ag72Cu28 wires embedded in borosilicate glass for imaging applications at mid-infrared frequencies. Initial numerical modeling indicates smaller optical losses for such a system in comparison to the equivalent Sn/soda-lime structures reported recently in the literature. Modeling of the proposed and fabricated magnifying hyperlenses shows promising overall optical losses between 11 dB to 16 dB (depending on the structural parameters) when operating at 5 μm wavelength. Their experimental characterization and the proof-of-concept far-field sub diffraction imaging experiment are in progress.
