AB - A broad band electromagnetic extraction method of the
dielectric tensor for nematic liquid crystals, associated to a
measuring cell, is presented. The dielectric tensor is computed
from S-parameter measurements obtained at the input planes of
a coplanar waveguide supporting the nematic liquid crystal to be
characterized, which is used as measuring cell. The extraction
method of the dielectric tensor is based on the propagation of the
dominant mode in the measuring cell. It is fast and easy. It uses
analytical relationships, which are presented in this paper. The
simulations results have demonstrated the validity of this
extraction method in the 1GHz-40GHz frequency range for the
electromagnetic characterization of nematic liquid crystals.
