| Abstract: | Time domain reflectometry method has been used in the frequency range of 10 MHz to 10 GHz to determine dielectric properties
of aqueous sucrose in ethanol. The dielectric parameters, i.e., static dielectric constant and relaxation time were obtained
from the complex permittivity spectra using the non-linear least squares fit method. The Luzar theory is applied to compute
the cross-correlation terms for the mixtures. It adequately reproduces the experimental values of static dielectric constants.
The Bruggeman model for the non-linear case has been fitted to the dielectric data for mixtures. |
