The comparison of electrooptical properties of PDLC liquid-crystalline composites in visual and near-IR ranges
Journal Title: Bulletin of the Military University of Technology - Year 2017, Vol 66, Issue 3
Abstract
Electrooptical properties of conventional Polymer-Dispersed Liquid Crystals (PDLC) composites were compared in visual and near-IR ranges for the electrically-induced light transmission effect. It was confirmed that the most important for the optical contrast value is the matching of refractive indices of the polymer matrix and dispersed droplets of liquid crystal, as well as matching droplet size and wavelength of incident radiation. The optimization of electrooptical parameters of such materials needs new liquid-crystalline mixtures dedicated for near-IR range. The studied effect can be applied for manufacturing window glasses with electrically adjusted transmission of infrared radiation.

Realization of coprocessor which supports counting of discrete logarithm on elliptic curves with partial knowledge
In this paper we analyse realization of a coprocessor which supports counting of discrete logarithm on elliptic curves over the field FG(p), where p is the large prime, in FPGA. Main idea of the realization is based on u...

Study of properties of nonwoven filter cartridges for the intake air of a car engine
The sources of atmospheric air pollution are presented. It has been shown that dust is a major component of the intake air of internal combustion engines. The impact of dust on the accelerated wear of the engine componen...
Modelling of damping forces occuring in simple MEMS systems
A certain damping force occurs in the micro-mechanical systems referred as MEMS. At the design stage of such systems, these forces must be accurately estimated. As shown in this work, in all systems operating at low freq...
