Structured Electromagnetic Materials Group

The Structured Electromagnetic Materials Group is dedicated to multidisciplinary fields including photonic crystals, metamaterials, nanoplasmonics, and graphene. We aim to study fundamental physics of light-matter interaction at the nanoscale, and to develop advanced optical nanostructures for practical applications.

Our research focus is on theoretical and experimental investigation of new wave phenomena and light-matter interactions in artificially structured materials. It includes the development of microscopic and semi-calssical frameworks for the optical response of nano-engineered geometries, the study of extreme light confinement and nonlocal response in nanoplasmonics using electron energy loss spectroscopy, and the exploration of advanced nanostructures for color effects, photovoltaics, and light-emitting devices. More information can be found under Research and Publications.

If you have any questions or comments, feel free to contact our Group members.
