Abstract
The study accomplished by Costa et al [EESC/USP, 2000]in your doctorate allowed to find physical and electric models that aided excessively in the understanding of the mechanisms of dielectric dispersion involved in the nematic liquid crystals (NLCs) (BDH - chemicals ltda). Besides, the electric models represented in a frequency range wide (0,1Hz to 1E7Hz)contributing for that a new senso…
