Formation and Properties of New Types of Metal–Dielectric Nanostructures for Creating Optical Metamaterials

Resumo

“Herein, we consider the technologies of obtaining composite structures that can exhibit the properties of metamaterials, namely layered metal–dielectric (metal–polymer) structures and fish-net metal-polymeric structures. The dielectric and resonance properties of the synthesized structures are studied both theoretically and experimentally, and the excitation features of new types of quasi-non-diffraction plasmon-polaritons generated in them are established. Original methods and tools for characterizing the optical properties of the created composite structures (in particular, a differential polarization interferometer, a method and a device for detecting a negative refractive index) are proposed. Based on the developed and created metamaterials, a number of new devices are proposed and implemented, in particular, new configurations of flat lenses (so-called superlenses) of the near and far fields in the spectral range from ultraviolet to infrared radiation”.
