We propose and demonstrate the fabrication of wire array metamaterial bers and hyperlenses based on Ag_(72)Cu_(28)wires embedded in borosilicate glass for imaging applications at mid-infrared frequencies. Initial numerical mod-eling indicates smaller optical losses for such a system in comparison to the equivalent Sn/soda-lime structuresreported recently in the literature. Modeling of the proposed and fabricated magnifying hyperlenses showspromising overall optical losses between 11 dB to 16 dB (depending on the structural parameters) when oper-ating at 5 μm wavelength. Their experimental characterization and the proof-of-concept far- eld subdi ractionimaging experiment are in progress.
