Modelling the diffraction of light by structures with spatial periodicity of the optical parameters of the substance and of the surface relief

Paper No P9: Diffraction on Anisotropic Substrates With Sinosoidal Surface Microrelief

“…In the case of investigation of oblique incidence influence on the diffraction orders' intensity the incidence angle was varied in range from 0 to 30° and then the intensities in every positive and negative order were compared. In the OAGSM method, every system is divided by a definite numbers of intermediate layers . The calculation accuracy depends on the layers number.…”

“…use polarization conversion and surface microrelief . The software optically anisotropic grating with surface microrelief (OAGSM) developed by us earlier provides calculation of diffraction efficiency for optically anisotropic gratings with periodical surface microrelief. In this software has been used to calculate light diffraction on birefringent substrates with symmetric rectangular and sine microrelief for its period reduced to the light wavelength Λ/ λ = 3.3.…”

Advanced Optical Materials Modified with Carbon Nano‐Objects

“…It is well known that electro-optical nematic liquid crystal (NLC) structure is a good model in order to consider the realistic technical cells as laser radiation switching devices, electrically and optically addressed spatial light modulators, and analogs of display elements [40][41][42][43][44][45]. Mostly liquid crystal (LC) cells, namely from the cyanobiphenyl group (see Figure 7.17[a,b]), operate in S-and T-confi gurations that realize a planar orientation of the LC mesophase on the aligning substrate surface.…”

As is well known, rubbing of the glass substrates or irradiation of them by holographic methods also leads to the planar orientation of LC molecules [40][41][42][43][44][45][46].

Effect of the Microrelief Surface of Periodic Anisotropic Structures on Their Diffraction Properties

“…Оптически анизотропные полимерные материалы с микрорельефом и процесс приготовления образцов описаны в [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Для компьютерного моделирования дифракции на структурах с пространственной периодичностью оптических параметров вещества и рельефа поверхности было рассмотрено прохождение света через слоистую двулучепреломляющую структуру с периодическим изменением показателей преломления и поверхностным микрорельефом.…”
