- Аннотация: Structure of the near field (intensity and polarization distribution, the latter is described with the generalized three-dimensional Stokes parameters) of a spherical Si subwavelength nanoparticle in the non-magnetic and non-absorbing media near a dielectric substrate has been studied in detail with the help of Mie theory and an extension of Weyl's method for the calculation of the reflection of dipole radiation by a flat surface. It is shown that for the nanoparticle near the substrate the interference effects due to the scattering by the nanoparticle and interaction with the substrate play an essential role. We also demonstrate how these effects depend on the dielectric properties of the nanoparticle, its size, distance to the substrate and polarization, wavelength and angle of the incident light field.
