R. Thomas et Dc. Dube, EXTENDED TECHNIQUE FOR COMPLEX PERMITTIVITY MEASUREMENT OF DIELECTRICFILMS IN THE MICROWAVE REGION, Electronics Letters, 33(3), 1997, pp. 218-220
An extended cavity resonance method using the TE10n mode is discussed
for measuring complex permittivity of dielectric films and foils of fl
exible dimensions nondestructively. Working relations for dielectric p
arameters epsilon' and epsilon '' are obtained on extending the validi
ty of conventional cavity perturbation technique. Results of measureme
nts performed on mylar are presented. The method is suitable for the d
etermination of complex permittivity of dielectric thin films.
