Microwave dielectric properties of strontium barium cerium niobate ferroelectric ceramics using cavity perturbation technique

Dielectric properties of strontium barium cerium niobate ceramics at the S band of microwave frequencies are studied using a network analyzer. The microwave cavity perturbation technique is employed for this study. Dielectric parameters such as complex permittivity and conductivity of strontium barium cerium niobate ceramics are determined by measuring the changes in the resonant frequencies and Q values of the cavity, due to the introduction of the sample.
