Optical properties of MgB2 nanostructured films. (a, b) The real and imaginary parts of the refractive index (a) and the dielectric function (b) for the plasmonic MgB2 bulk metal based on approach of44 (Table S2). (c) Comparison of the complex refractive index evaluated from ellipsometric measurement and theoretically simulated dependences based on polarizability of the discs-like nanostructures with strong LSPRs. (d) The real and imaginary parts of the dielectric function for the plasmonic MgB2 nanostructured films: experimental and theoretical dependences.
