Abstract :
The measurement of high dielectric constants materials in a coaxial line, using an automatic network analyser (ANA), must take the actual diameter of the sample into consideration. The error on the measured epsilon r value may be approximated by the fractional diameter deviation times epsilon r2. A correction method is proposed.
