Abstract
Parallel and perpendicular components of the dielectric constant for 5CB nematic liquid crystal are measured in a relaxation region. Two frequencies f1≈30 and f2≈350 MHz are determined at which the inversion of the dielectric anisotropy sign is observed. It is shown that the observed sizable high-frequency shift of f2 with respect to the value calculated according the Debye theory is caused by the dielectric resonance near the relaxation region.
