Brief CV

Dr. of Science Igor S. Nefedov is an internationally recognized  expert in bianisotropic media, numerical methods for bianisotropic media waveguides and wire media, ferrites, metamaterials, including hyperbolic metamaterials (HMMs), plasmonics, thermal emission and thermal radiative heat transfer. He has suggested a new concept of exploitation of hyperbolic metamaterials, so-called asymmetric HMMs, for perfect absorbers and thermal emitters.  He proposed (with C. Simovsky) to exploit HMMs for giant enhancement of the radiative heat transfer between bodies. Now this approach is intensively developed in several research groups. Igor Nefedov has published more than 150 papers in referred journals and many conference papers. His h-index is 18 in ISI Web of Science and his works are cited more than 1500 times  in ISI Web of Science. In this project his expertise in plasmonics and hyperbolic metamaterials is planned.

Research interests:

Hyperbolic metamaterials; thermal energy heat transfer; thermal emission; electromagnetic properties of carbon nanostructures (carbon nanotubes, graphene); absorbers.
