Recently, the University of Exeter provided research demonstrating how graphene’s properties can be utilized to create artificial structures that can be used to control and manipulate electromagnetic radiation over a wide range of wavelengths.
Scientists at the University of Exeter “combined nano-ribbons of graphene, in which electrons are able to oscillate backwards and forwards, together with a type of antenna called a split ring resonator. Careful design of these two elements leads to a system which strongly interacts with electromagnetic radiation,” Phys.org reported.
“One of the key characteristics of our structure is that it has the effect of focusing the electromagnetic radiation into an area much smaller than its wavelength. This could potentially lead to new ways of undertaking ultra-high resolution spectroscopy of, for example, bio molecules,” Professor Nash, the Director of Natural Sciences at Exeter, said.
According to Phys.org, the research was part of the EU FET Open Project GOSFEL , which aims to develop a new laser source for applications such as gas sensing.
