Abstract: | Due to the relaxation of the longitudinal dielectric constant, the dielectric anisotropy in a nematic liquid crystal may change sign and become negative. This gives rise to a conduction regime with negative dielectric anisotropy at high frequencies. The width and cutoff frequency of this conduction regime are calculated. |
