Selective optical reflection in the fog phase
Demikhov E. I., Dolganov V. K., Krylova S. P.
The optical scattering spectrum of the fog phase of a liquid crystal has been measured. This spectrum is found to be wavelength-selective. The half-width of the diffraction peak exceeds the diffraction half-width in the BP I and BP II quasicrystalline phases. The wide-band nature of the spectrum is evidence that there is no long-range order in the fog phase.
