Super-resolution in diffractive imaging from hemispherical elastic light scattering data.

Angle-resolved hemispherical elastic light scattering techniques have been used to reconstruct the surface profile of two-dimensional photonic crystals with submicron resolution and metrological precision. Iterative algorithms permit subsequent calculation of a surface autocorrelation function with additional numerical approximation of the power spectrum and then yield final reconstruction of the surface shape. The proposed method enables filtering out unwanted scattering background, precluding the convergence of phase-retrieval algorithms.

Scattering of surface plasmon-polaritons and volume waves by a rough gold film.

A discrepancy between the theories of volume and surface plasmon-polaritons (SPPs) wave scattering was found. Its tentative explanation is related to the resonance-like emission of SPPs energy due to SPPs diffraction by a surface relief Fourier decomposition component. It was also shown that the sum of surface wave scattered intensity along a plane of incidence is proportional to surface roughness value.

Fabrication and properties of ITO films treated by excited atomic oxygen.

We consider the crystallization of ITO films induced by excited atomic oxygen. Owing to it, transmittance of these films in visible ranges increased by ~20% and surface impedance dropped from 36 down to 4.6Ω/□.

Giant enhancement of elastic surface plasmon-polariton scattering.

Here we report the first (as far as we know) experimental observation of extremely high enhancement factor due to elastic surface plasmon-polariton scattering by surface singularities.We have observed strong diffraction of surface plasmon-polaritons by shallow diffraction grating while its illumination by evanescent or volume waves do not shows any traces of diffraction structure in space distribution of scattered light.

Elastic laser light scattering by GaAs surfaces.

Angle-resolved scattering (ARS) intensities were measured in the backscattering hemisphere for the (1 0 0) and (1 1 1) faces of GaAs single crystals. Three epitaxial layers were deposited onto the GaAs (1 0 0) single-crystalline wafers. The laser elastic light scattering shows the presence of a regular surface microrelief whose orientation corresponds to the crystallographic axes in the surface plane.
