Abstract :
A combined total reflection-transmission method for permittivity measurements at radio and microwave frequencies is described. Analytical expressions for the dielectric constant and the loss factor of a sample, viewed as a two-port in the transmission system, in terms of the measured scattering parameters are given. ne uncertainty of measurements of the dielectric constant and the loss factor is discussed and a method ofselecting an optimum sample length is suggested.
