A group of general scientists, led by Professor Geoff Nash from a University of Exeter, have engineered a conspicuous new hybrid structure, or metamaterial, that possesses specific characteristics that are not found in healthy materials.
The collaborative group total nano-ribbons of graphene, in that electrons are means to teeter retrograde and forwards, together with a form of receiver called a separate ring resonator.
Careful pattern of these dual elements leads to a complement that strongly interacts with electromagnetic radiation. In these experiments a group used light with really prolonged wavelengths, distant over what a tellurian eye can see, to uncover that these new structure can be used as a form of visual switch to interrupt, and spin on and off, a lamp of this light really quickly.
The collaborative general research, including experts from a University of Exeter, England, and teams led by Dr Sergey Mikhailov during a University of Augsburg, Germany, and Professor Jérôme Faist during ETH Zurich, is published in reputable systematic journal, Nature Communications.
Professor Geoff Nash, from a University of Exeter’s Department of Engineering said: “In these novel formula we denote a new form of structure that can be used not usually as an sparkling exam bed to try a underlying new science, though that could form a basis of a operation of technologically critical components”.
The investigate was carried out as partial of a EU FET Open Project GOSFEL , that aims to rise an wholly new laser source for applications such as gas sensing. Professor Nash now also binds an EPSRC in Frontier Manufacturing.
Professor Nash, who is also Director of Natural Sciences during Exeter added: “One of a pivotal characteristics of a structure is that it has a outcome of focussing a electromagnetic deviation into an area most smaller than a wavelength. This could potentially lead to new ways of endeavour ultra-high fortitude spectroscopy of, for example, bio molecules. Working with colleagues in Biosciences we are already starting to try some of these effects, with undergraduates from a innovative interdisciplinary Natural Sciences programme, and postgraduates from a Exeter EPSRC Centre for Doctoral Training in Metamaterials.”
