Deformations of nematic layers induced by d.c. electric field were studied numerically. The nematic liquid crystal under consideration possessed flexoelectric properties. Its dielectric anisotropy was zero, so the deformations were solely of flexoele

Dynamics of DC electric field induced deformations of flexoelectric nematic layers were studied numerically. The characteristic response times were calculated. It was found that the cooperative effect of flexoelectricity and of ionic space charge may

Formulae used for description of anchoring energy of nematic liquid crystal aligned on solid substrates are reviewed. They are based on macroscopic approach considering the concepts of the easy axis and of the anchoring strength parameters. Propertie

Niewielkie odkształcenia wywołane polem elektrycznym w warstwach skręconego nematyka były symulowane numerycznie. Badano odkształcenia jednowymiarowe (tj. jednorodne na całej powierzchni warstwy) i dwuwymiarowe (tj. przestrzennie okresowe). Wyk

Electric field induced deformations occurring in twisted nematic cells filled with liquid crystalline material possessing flexoelectric properties were simulated numerically. The aim of computations was to compare the two-dimensional periodic deforma

The deformations of homeotropic nematic layers induced by ac electric field of frequency f were studied numerically. Two kinds of nematic liquid crystals with small negative dielectric anisotropy, De < 0, were considered: (i) the non-flexoelectric ne

Ionic current flowing in a thin layer of dielectric liquid under the action of square wave voltage was studied numerically. Quasi-blocking electrodes and equal mobilities of anions and cations were assumed. Field dependent dissociation and recombinat
