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.

Scattering and reflective properties of ordered mesoporous silica films.

Ordered mesoporous and nonporous silica films were studied by analysis of reflection spectra and hemispherical elastic light scattering (HELS). The real and imaginary parts of the index of the films were estimated from the reflection spectra. The HELS angular distribution of the mesoporous film shows a minimum, which has been interpreted as an interference pattern coming from the beams scattered by the mesopores.

Elastic light scattering with a LiNbO3 waveguide.

We present the measurements of hemispherical elastic scattering of light guided by different modes of a planar LiNbO3 waveguide. It is shown that the fundamental and the lowest-order modes are more sensitive to the scattering properties of the air-core interface, whereas higher-order modes are more sensitive to the optical inhomogeneities of the core-substrate interface. We also demonstrate that because of static polarization of LiNbO3 crystal, the air-core interface is sensitive to the presence of dust particles in air, which causes a change in the scattered light based on time of observation.
