Microwave methods of ferroelectrics and related materials investigation

Abstract

Ferroelectric materialspsila distinct feature is large dielectric permittivity epsiv which sometimes is accompanied by the large loss tangent tandelta. Often this becomes an obstacle to conduct their accurate characterization despite of variety of techniques available. This report is devoted to the selection of proper method for specific cases of bulk or film materials investigation to obtain reliable data of their epsiv and tandelta.
