Acoustic Remote Sensing Piezoceramic Transducers with Internal Screen

The analytical relationships, allowing to quantify the parameters of the cylindrical piezoceramic transducers with internal screens for remote sensing acoustic fields by means of the related fields method in multiply assessments of the resonance radiation spectra and the angular distribution features of acoustic fields at the resonant frequencies depending on the particular design of the sensing device are obtained. This became possible by taking into account connectivity of the acoustic, mechanical and electric fields when converting acoustic energy and acoustical relationship between the piezoceramic shell and the screen inside the transducer cavity.
