Abstract
Complex dielectric permittivity spectra, in the frequency range 10 MHz to 20 GHz are reported for aqueous Cesium chloride (CsCl) & Lithium chloride (LiCl) solutions at 250C using time domain reflectometry technique. The static dielectric constant, relaxation time and conductivity have been determined using nonlinear least squares fit method. The TDR technique is based on the study of the change in shape of a fast rising voltage step which is propagated through coaxial line section filled with the material under study. The voltage pulse, registered by fast sampling scope, is then compared with that reflected from the sample cell. Fourier transformation of both the pulses gives the Frequency dependent complex dielectric permittivity.
