Diffraction on Anisotropic Substrates with Sinusoidal Surface Microrelief

open access: yesMolecular Crystals and Liquid Crystals, 2014
Light polarization management by diffractive optical elements (DOE) can enhance light efficiency in LCD backlight systems. The OAGSM software developed earlier provides calculation of diffraction efficiency for optically anisotropic gratings with periodical sinusoidal surface microrelief.

Microrelief induced by tillage: measurement and modelling of Surface Storage Capacity

open access: yesCatena, 2002
Abstract The micro-topography of a groundnut plot in Senegal has been recorded over a full cultivation cycle, using an automated device able to measure 16.2 m2 at every 5 cm with an accuracy of 1 mm. Tillage is horse drawn, perpendicular to the general slope, and generates oriented microreliefs.

Optimization of the parameters of a partially regular microrelief by vibration rolling method [PDF]

open access: yesE3S Web of Conferences, 2021
Experience of operating machines shows that their quality depends on the nature of the contact of mating parts. The irregular nature of the surface microrelief, which is due to traditional treatment methods used, arises difficulties in solving three main

Ensuring a Stable Relative Area of Burnishing of Partially Regular Microrelief Formed on End Surfaces of Rotary Bodies

open access: yesJournal of Mechanical Engineering, 2021
The scheme of arrangement of grooves of partially regular microrelief of type II shifted by 0.5 angular pitch is considered. Such grooves are formed by vibration on end faces of rotary bodies.

Effects of fabrication errors on the focusing performance of a sector metalens [PDF]

open access: yesКомпьютерная оптика, 2018
Using e-beam lithography, a 16-sector spiral metalens was fabricated in an amorphous silicon, capable of converting linearly polarized incident light into an azimuthally polarized optical vortex. When illuminated by a 633-nm linearly polarized laser beam,
