Hybrid anchoring for a color-reflective dual-frequency cholesteric liquid crystal device switched by low voltages
Cholesteric liquid crystal (CLC) materials used in electro-optical (EO) devices are characterized by high operating voltage and slow response speed, which hinders their further development in display applications. ...
Geometric phase and o-mode blueshift in a chiral anisotropic medium inside a Fabry-P´erot cavity
Anomalous spectral shift of transmission peaks is observed in a Fabry-P´erot cavity filled with a chiral anisotropic medium. The effective refractive index value resides out of the interval between the ordinary and ...
Mathematical Model and Numerical Simulation of Aluminum Casting and Solidification in Magnetic Fields with Allowance for Free Surface Dynamics
A complex mathematical model of aluminum casting and solidification in a variable electromagnetic field is constructed. The model is based on the solution of magnetohydrodynamic equations and the VOF method. Test results ...
Nanocomposite Material Based on Ultra-High-Molecular-Weight Polyethylene and Titanium Dioxide Electroarc Nanopowder
The effect of nanodisperse TiO2 powder additions obtained in low-pressure arc discharge plasma on the physicomechanical properties of the ultra-high-molecular-weight polyethylene (UHMW-PE) samples obtained by hot molding ...
Structure of the organic matter pool in Pinus sibirica dominated forests of Central Siberia
Organic matter pool and its distribution between growing stock, dead wood and windfall in upland and lowland Pinus sibirica dominated forests of Central Siberia (along the Yenisei River) is evaluated. The average growing ...
Theory of second-harmonic generation in achirped 2D nonlinear optical superlattice under nonlinear Raman-Nath diffraction
We analyze second-harmonic generation (SHG) in a two-dimensional nonlinear optical superlattice (NLOS) with its modulation period being chirped in the propagation direction and constant in the transverse direction. This ...
