Research of electrical impedance of piezoelectric disk in middle frequencies area

Disk piezoelectric devices are widely used in the elements of information systems. The multiplicity and variety of the practical application of disks with sector electrodes naturally stimulates theoretical studies, the purpose of which is to predict the characteristics and technical parameters of piezoelectronic devices that are created on their basis. Prediction is based on a mathematical model, which is the main result of a theoretical description of a real device
