Abstract :
In this paper the determination of the permittivity of liquid or homogeneous dielectrics from their time-domain response is addressed. The analysis is based on a simplified model of the TDR measurement setup, where the probe is described by an ideal transmission line with a Debye permittivity. A simple formula to evaluate the permittivity is introduced, and compared with other well-known methods for the permittivity determination based on the calculation of the travel time of the TDR signal along the probe.
