Dr. Tim Raybould
Former Project
Transforming electromagnetic wavefronts with metamaterials.
Short CV
Tim received his MPhys (Physics with Study in New Zealand) from the University of Exeter in 2012.
Over the course of his Masters, he conducted research concerning the use of graphene-based thermoacoustic devices, graphene field-effect transistors and non-linear optics.
Tim joined the Optoelectronics Research Centre as a PhD student in September 2012, with research focussing on toroidal metamaterials.
