Abstract

We have described a novel mechanism of the kinklike pressure P(z-vt) response of the microsized twisted nematic volume under the effect of externally applied electric field E directed parallel to the restricted surfaces and induced by a strong local disturbance of the director field n[over ̂]. It is found that the torques acting on the director n[over ̂] may excite the pressure traveling wave spreading along the normal to both boundaries, whose resemblance to a kink-like wave increases with increasing the value of the applied electric field greater than some critical value E_{cr}.
