Logarithmic derivative complex permittivity spectrometry

open access: yesMeasurement Science and Technology, 2003
A frequency domain method for the advanced dielectric spectrometry of liquids is proposed. It utilizes the feasibility of simultaneously measuring the input admittance or reflection coefficient of the specimen cells and the derivative of these cell parameters with respect to frequency using modern input impedance or network analysers.
