“…Both azimuthal (in-plane) and zenithal (outof-plane) gliding have been observed in the presence of externally applied electric [1,2,3,4] or magnetic fields [5,6]. Various workers have suggested that gliding can be the result of adsorption and desorption of the liquid crystal on the polymer surface [7], of a mutual reorienting of the liquid crystal and polymer network [2,5,6] or of sublayers with different physical properties near the polymer surface [7,8]. It has also been demonstrated that gliding is not restricted to polymers with weak anchoring energy, so-called 'soft' polymers [3,4].…”

“…Some phenomenological description of surface dynamics was proposed by a number of authors [143,153,[156][157][158][159][160][161]. In particular, they explain some features of extremely slow field-induced motion (gliding) of an easy axis n e defining the preferable surface direction of a liquid crystal.…”

“…As an example of a phenomenological model, incorporating both fast and slow surface dynamics, we can consider a sublayer model proposed to explain experimental results of azimuthal gliding at a weak surface anchoring, induced by strong in-plane electric field [159] or by a combined action of electric field and light [161].…”
