Abstract :
Peculiar feature of ferroelectrics is high dielectric permittivity epsiv which sometimes is accompanied by very big loss tangent tandelta. This is a reason of difficulties to obtain accurate characterization despite of variety of techniques available. This report is devoted to the selection of proper waveguide method for specific cases of bulk or film materials investigation to obtain reliable data of their epsiv and tandelta.
