Аннотация
The type of changes in the total input conduction and its active and reactive components has been analyzed for an ultrasonic transducer with two independent piezoelectric plates separated by a dielectric layer as compared with the case of in-phase excitation of the transducer. Results of calculating the efficiency are considered for different transducer designs in accordance with a synthesisproblem solution that ensures a uniform amplitude-frequency response and a linear phase-frequency characteristic of emission.
