Microwave absorption properties of ferroelectric piezoceramic materials

The results of a study in the microwave range of the microwave absorbing properties of piezoceramic materials developed at the Scientific Research Institute of Physics of the Southern Federal University and based mainly on the PbTiO$_3$–PbZrO$_3$ system are presented in comparison with industrial composite materials based on carbonyl iron and epoxy resin and materials of industrial dielectric resonators. A technique for measuring and calculating the parameters of samples of the materials under study is described. The relationship between the microwave absorbing properties of the ceramics under study and their phase composition has been established. An assessment has been made of the applicability of the developed piezoceramic materials in microwave technology devices
