Structure of a hybrid aligned cholesteric liquid crystal cell

It comes immediately from the previous equation that the helix of a cholesteric liquid crystal must rotate at a constant angular velocity ω when it is subjected to a

We have explored methods to prepare cholesteric liquid crystal emulsions by means of ultrasound, condensation as well as a coaxial microfluidic technique. Our results suggest that

Within a relatively large central area the light is generally elliptically polarized across a broad wavelength spectrum, a result of a combination of selective

reflection in the near-infrared (most shells in Figure 5b), red (Figure 5d and the two leftmost shells in Figure 5c), or green (the shell on the left in Figure 5b and the four

Clusters of planar-aligned short-pitch cholesteric liquid crystal spheres generate dynamic colour- ful patterns due to multiple selective reflections from the radially

Reflection patterns from planar-aligned droplets (a) and shells (b) of a cholesteric liquid crystal with pitch in the range of generating red selective reflection (central,
