Abstract

We study hydrodynamic instability of nematic liquid crystal (NLC) in a biharmonic electric field. The instability is found to strongly depend on the frequency difference; namely, if the applied frequencies of the electric field are close one to another, the critical voltage of Williams domains behaves as the square root of the frequency difference. The 'germination' and 'winking' of the generated structure is exhibited also by the same condition. In the special case of a significant frequency difference, the threshold field of the instability increases with the higher frequency and eventually tends to a constant value. Theoretical explanation of the observed phenomena is given.
