Chiral Metamaterials for THz Polarisation Control

Project description

High-performance metamaterials interacting with terahertz waves

A metamaterial is an artificial composite structure engineered to have properties not found in naturally occurring materials. Chiral metamaterials are designed to have unnatural chiral parameters. Funded by the Marie Skłodowska-Curie Actions programme, the CHARTIST project aims to lay the theoretical basis for the development of a proof-of-concept chiral metamaterial, enhanced by graphene and carbon nanotubes, that interacts at terahertz frequencies. The project will rely on solid theoretical background on analytical and numerical modelling of the terahertz radiation interactions with chiral metamaterials and metasurfaces. New techniques for controlling helicity in the terahertz range will be studied. Furthermore, innovative techniques will be used to fabricate chiral metamaterials and metasurfaces, including femtosecond laser micromachining and electron-beam lithography.

Objective

Based on chiral metamaterials and metasurfaces enhanced by graphene and carbon nanotubes, this project aims at providing theoretical basis, performing proof of concept experiments, and building a prototype device for unprecedented dynamic control of THz-wave polarization. The project relies on solid theoretical background that will enable analytical and numerical modelling interaction of the THz radiation with chiral metamaterials and metasurfaces and will also reveal the most promising techniques to control helicity in the THz range by external stimuli. The chiral metamaterials and metasurfaces will be fabricated by advance fabrication techniques including femtosecond micromachining of multilayer substrates, molecular beam epitaxy and e-beam lithography. The enhancing of the fabricated chiral structures with graphene will provide additional channels for manipulating the helicity-sensitive transmittance and reflectivity, which can be employed for the THz polarization control. The proposed research program implemented via intersectoral and international mobility and connected training, dissemination and outreach activities will enable the knowledge and technology transfer, wider professional networking, acquiring new skills and exploitation of project results by European THz industry. In parallel, the world-wide professional CHARTIST network will considerably enhance the future career prospects of early stage researchers and widen the professional opportunities for experienced researchers involved.
