Dr. Artemios Karvounis

Project
Nanostructured photonic metamaterials

Short CV
Artemios received his 4-year Degree in Physics with emphasis in Electronics & Telecommunications from the National and Kapodistrian University of Athens, Greece in 2011, where he conducted research in composite right/left-handed transmission line metamaterials. After this he attended the MSc programme in Electronics & Radioelectrology, at the same Institution. Artemios joined the Optoelectronics Research Centre as a PhD student in October 2013, with research focussing on dielectric and optomechanical photonic metamaterials
