This project aims to provide theoretical and experimental basis, to perform proof of concept experiments and to build prototypes of the thinnest ever alignment–free components of the THz photonics.

Being based on 2D Dirac semimetals (graphene, silicene, germanene) and metamaterials paradigm, the fabricated lenses, filters and polarizers will be capable to outdoing the existing ones in terms of performance, footprint and tunability in lab-on-chip integrated solutions. The project relies on solid theoretical background that will enable calculation of the constituent parameters of 2D semimetals with account for defects, doping, stacking, strain and external fields using ab initio and tight binding approaches. The advances in electromagnetics will be employed to reveal physical phenomena underlying the response of both individual Dirac semimetal based metaatoms and their arrays in the THz spectral range.

From the experimental side, the DiSeTCom will feed into the development of feasible and easy to use techniques for fabrication of metasurfaces based on graphene/silecene/germanene that will lead to prototype of tunable THz passive components with unprecedented performance. Robust design and sensitivity analysis will allow us to develop revolutionary THz devices thereby contributing to the European technology and creativity through joint R&D and R&I multisectorial and international cooperation activities supported by knowledge sharing. 

The consortium will implement research/innovations by means of functional secondments and organization of training courses, research/industrial workshops aimed at knowledge and technology transfer, wider professional networking, acquiring new skills and exploitation of project results by European THz industry. Implementation of the DiSeTCom will bring in considerable enhancement of the potential and future career prospects of the researchers involved via well balanced profiles and world-wide professional network of the consortium.
