Characterization of slow chemical reactions is essential for assessing catalytic efficiency in chemistry and biology. Traditionally, chemical reaction rates are obtained from population relaxation kinetics measurements and the Arrhenius equation. Unf

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

Metamaterials for the mid-infrared spectrum require subwavelength meta-structures with dimensions of a few hundreds of nanometers. Fabrication via fiber drawing is challenging as the Plateau-Rayleigh instability caused by interfacial surface tension
