Оn thе influence оf acoustic attenuation in thе transducer layers under thе excitation оf thе volume elastic waves by 6mm class piezoelectric with arbitrary orientation of axis 6
An electroacoustic transducer оn the bases оf the piezoelectric class 6mm with axis 6 arbitrary orientation with electrodes of final thickness regarding the acoustic attenuation in its layers is considered. The system оf equations for the computation the transducer impedance, longitudinal and shear wave radiation resistance, power ratio of these waves in the sound conductor, and also the conversion losses for longitudinal and shear waves is obtained. The numerical analysis results of attenuation effect in the specific transducer in the range of 15 GHz are given.
