Terahertz region is a part of the electromagnetic spectrum that lies between the radio waves and infrared/visible light. Terahertz rays can penetrate through cardboard, plastic, clothing, and many other materials, so that we can image a concealed weapon, or detect chemical and biological agents through sealed packages.
Terahertz technology in security portal applications has been demonstrated for detecting and identifying objects concealed on people and is a leading area of development and commercialisation.
The aim of our work is the development of a new generation of sensors/sources based on solid-state devices for application in terahertz range. This by exploiting recent advances in the plasma waves oscillations in a gated two-dimensional system.
Other activities cited below are also taken our interest:
- Development of a novel plasma waves devices operating at terahertz range which can integrate THz imaging/spectroscopy systems
- Fundamental studies of graphene (Low temperature and high magnetic field characterization.)
- Exploring new technology for terahertz range based on graphene material.
- MonteCarlo simulations on studied devices.
- Exploring new methods for characterization of solar cells
