Abstract
Aim. Theoretical modeling of optical parameters of a “dielectric – metal – dielectric” nanostructure taking into account the ellipsoidal metal band structure.
Methodology. The quantum theory of transport phenomena is applied, which involves the determination of the charge carrier density matrix diagonal components by solving the Liouville equation. Charge carrier surface scattering is taken into account by using Soffer boundary conditions.
Results. Analytical expressions for the optical coefficients and polarization parameters of reflected and transmitted waves were derived. It was shown that the isoenergetic surface anisotropy significantly influences the reflected wave polarization shape and the ability of the “dielectric – metal – dielectric” nanostructure to absorb radiation.
Research implications. The results of the work can be used to design polarizers based on layered “dielectric – metal – dielectric” nanostructures.
