Abstract
Parallel and perpendicular components of the dielectric constant for 5CB ne matic liquid crystal are measured in a relaxation region. Two frequencies f (1) approximate to 30 and f(2) approximate to 350 MHz are determined at whi ch the inversion of the dielectric anisotropy sign is observed. It is shown that the observed sizable high-frequency shift of f(2) with respect to the value calculated according the Debye theory is caused by the dielectric re sonance near the relaxation region.
