Abstract :
A modified lumped parameter method is discussed which is judged to be especially suitable for microwave measurements of dielectric dispersion in high dielectric materials in a particular frequency region. The method combines some of the features of the lumped parameter method and the distributed parameter method. Dielectric dispersions for PbZr1-xTixO3, BaTiO3, and Ba xSr1-xTiO3 ceramics in the frequency domain from 1 MHz to 1 GHz are presented. The principle of the measurement and the accuracy of the experimental data which are retrieved are also discussed
