Optical Properties of Two-Dimensional Layered Structures in the Infrared Range

Infrared optics is extremely widespread in modern science and technology. Almost all telecommunications equipment operates in the infrared range, thermal radiation is also most pronounced in the infrared region of the spectrum. Night vision devices are based on its detection. Therefore, infrared radiation plays an important role in nearfield radiative heat transfer and is also used in spectroscopy and many other scientific applications. In recent years, advanced nanostructuring techniques aimed at manipulating light at the nanoscale have become widespread. In particular, photonic crystals, metasurfaces and nanoresonators are actively used. In this work, we consider the possibilities of using two-dimensional layered structures in the optical and infrared ranges. In particular, we consider the possibility of using Dyakonov surface waves in confined media, as well as collective resonances in the lattices of plasmonic nanoparticles. Both types of structures make it possible to localize light on the submicroscale, enhance the interaction of light with matter, and effectively control the propagation of electromagnetic waves.
