A nematic liquid crystal (NLC) layer with the anisotropy axis modulated at a fixed rate q in
the transverse direction is considered. If the layer locally constitutes a half-wave plate, then …

Recent studies on the behavior of nematic liquid crystals (LC's) in two basic configurations
are described. The phase rate of change Δ?/Δt is studied for the case of parallel aligned …

We present a detailed study of self-phase modulation in nematic liquid crystals, performing a
quantitative comparison with the theory of diffraction. A quite satisfactory fit is obtained at low …

The optical wave propagation within liquid crystal structures is addressed by the
development of rigorous electromagnetic wave propagation methods. The demand of more …

Transverse-periodic-oriented nematic liquid crystals (LCs) are a special type of optical axis
grating that are capable of very high efficiency diffraction (theoretically, 100%) in thin layers …

In polymer aligned liquid crystal cells, a surface layer exists. In this surface layer the in-plane
distribution of the mesogens, the shape of the mesogens, and their average angle with the …

We present a method to simplify simulation techniques for determining liquid-crystal director
orientation in geometries with sharply defined edges and for surfaces with strong anchoring …

A micro-or nanopatterned planar-aligned cell ordinarily requires a pair of mirror-image
patterned substrates that must be aligned in register to⪡ 1 μ m⁠. As an alternative we …

Simple analytic solutions to the equations governing the nematic liquid crystal director
profiles under an external voltage and arbitrary anchoring energy, taking into consideration …

A new electro-optical material based on nematic liquid crystal dispersed in a polymer matrix
has recently been introduced by Fergason. This technology (termed NCAP, for nematic …
