Nanoplasmonics studies the interaction of light with metallic nanostructures, in which collective oscillations of electrons — plasmons — make it possible to localize the electromagnetic field at scales smaller than the wavelength of light. The optical response of such materials is determined not only by the choice of their chemical composition but also by their design and structural geometry. All this makes it possible to create media with properties unavailable to conventional optical materials, as well as to resonantly enhance various optical effects.
In our research, special attention is paid to hyperbolic metamaterials (HMMs) — artificial composites consisting of metallic nanorods embedded in a dielectric matrix. Such structures possess a number of features: pronounced optical anisotropy, nonlocal optical response, etc. This leads to the emergence of unusual properties of such structures — for example, the existence of the Epsilon-Near-Zero (ENZ) regime, in which one of the main components of the effective permittivity tensor becomes zero. Our laboratory has also conducted research on a number of other plasmonic nanostructures, such as magnetoplasmonic crystals, chiral plasmonic structures, and others.
To date, the following key results have been obtained in this area:
