Professor Stefan Maier from Imperial's Department of Physics, co-leader of the project, explains:
"With metamaterials, we can devise completely new ways of controlling radiation, from visible light all the way down to terahertz radiation and beyond. What we are aiming at are structures that are easy to make, but that can give us a level of control over the flow of radiation thought impossible until now. For example, we can make surfaces that guide terahertz or even radiofrequency waves along them, with their energy highly concentrated right there at the surface, extending only a tiny fraction of the wavelength away from it. This might greatly improve the sensitivity of terahertz sensing devices and allow new ways to harness low-frequency radiation."
The Imperial College London and University of Southampton research teams will also be focusing on developing metamaterials for use in energy harvesting, optoelectronics, fibre optics, as well as bionanotechnology and imaging.
