We describe the fabrication of metamaterial magnifying hyperlenses with subwavelength wire array structures for operation in the mid-infrared (around 3 µm). The metadevices are composed of approximately 500 tin wires embedded in soda-lime glass, whe

A flexible fiber-drawn material, i.e. polyurethane, allows for novel applications from THz to the visible. We exploit its elastic properties to generate orbital angular momentum modes, to make pressure sensors and to realize tunable metamaterials.

Extreme sub-diffraction focusing of THz radiation is obtained by cascading two metamaterial wire array fiber hyperlenses. A record 1/176 of the wavelength is achieved, allowing squeezing 8.8 mm wavelength to a 50 micron spot.
