About us

At META-IR, we investigate the infrared spectral and spatial properties of newly emerging materials as well as metamaterials, for taming and tuning of the infrared emitted radiation. The goal of the laboratory's research lies in the synergistic overlap of engineering, photonics, and materials science.
Our work is focused on the investigation of metamaterials and metasurfaces with tailored spectral response to set the basis for the realization of tunable and dynamically controllable systems as building blocks for the development of platforms for MIR functionalities including IR sensors and sources. To this aim, an ultimate generation versatile infrared interferometer (Invenio-FTIR) is available including angular reflectance unit with variable independent angles, polarized light with variable angles of both incoming and outcoming beams, high index ATR hemisphere crystal (ZnSe) with sample holder for customized experiments.


Research at META-IR is focused on tailoring spectral response, polarization behavior or angular emission features of materials and metastructures to advance in fields such as thermal management, chemical and bio- sensing and photonics in general. Newly emerging 2D materials as well as IR featured nanostructures allow several applications such as detection of traces of biomolecules and harmful/explosive substances [1], the realization of depolarizing optical components [2] adaptive emissivity elements [3] as well as devices for thermal imaging and for medical diagnostics.

Selective and tunable IR emission in polar metamaterials

Tuning an emissivity peak in 1 micron hBN film with cylindrical air inclusions to get a resonance at 1585 cm-1 to match the absorption line of a maker type 2 for diabetes (isoleucine).


Thermal filtering and infrared camouflage.

Phase change materials, such as thermochromic vanadium dioxide, display versatile, adaptable IR emission features under different heating regimes, and allow the design of active thermal devices.
