Applied electric field effect on light-scattering birefringence of dye-doped liquid crystal molecule and consistent neural network empirical physical formula construction for scattering intensities
Polat, Omer; Yildiz, Nihat; San, Sait Eren (ELSEVIER SCIENCE BV, 2011)In this paper, we realized two objectives. Firstly, birefringence of azo and anthraquinone dye-doped nematic liquid crystal (NLC) molecules was investigated by applied electric field dependent laser scattering intensities. ... -
Consistent neural network empirical physical formula constructions for nonlinear scattering intensities of dye-doped nematic liquid crystals with ultraviolet pump laser-driven Fredericksz threshold shifts
Polat, Omer; Yildiz, Nihat; Akkoyun, Serkan (ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2018)Intrinsic high nonlinearity in experimentally measured laser scattering intensities poses significant difficulties in analyzing various molecular and optical properties of nematic liquid crystals (NLCs). In this respect, ... -
Investigation of the Mueller Matrix elements of the liquid crystal cell illuminated with a broad band light source
Polat, Omer; Emul, Yakup; Ozharar, Sarper (SPRINGER, 2017)The Mueller Matrix (MM) elements of the planar liquid crystal cell which is illuminated with a broad band light source was investigated and six MM elements were experimentally measured as functions of wavelength in the ... -
Light-scattering determination of visco-elastic and electro-optic parameters of azo and anthraquinone dye-doped liquid crystal molecules and consistent neural network empirical physical formula construction for scattering intensities
Yildiz, Nihat; Polat, Omer; San, Sait Eren; Kaya, Nihan (ELSEVIER SCIENCE BV, 2011)In this paper, we achieved two aims. Firstly, laser light-scattering intensities in methyl red (MR) azo and disperse red (DR) anthraquinone dye-doped nematic liquid crystal (NLC) molecules were measured versus scattering ... -
Light-scattering experiments in dye-doped liquid crystals both to determine crystal parameters and to construct consistent neural network empirical physical formulas for scattering amplitudes
Yildiz, Nihat; San, Sait Eren; Polat, Omer (ELSEVIER SCIENCE BV, 2011)The aim of this paper is two-fold. Firstly, static laser light-scattering amplitude measurements in azo-dye doped nematic liquid crystals (NLCs) were made versus scattering angle, temperature and applied bias voltage. Three ...
