Formation of scattered field of electroelastic cylindrical transducer in a closed layer

N.Yu. Filipova, A.V. Korzhik
Annotations languages:

The angular distribution of the scattered pressure and complete the fields created by the reception electroelastic cylindrical piezoceramic transducer with an acoustically soft, acoustically tough and resilient annular layer in the "through" staged at different frequencies. It is shown that the combination of acoustic qualities and a layer of piezoelectric membrane with variable acoustic stiffness alters the scatterplot. It is established that the presence of an acoustically soft or acoustically rigid layer modifies the total field compared to the same field without a converter layer and the elastic layer to the character of the complete field coincides with the field of a cylindrical shell without layers of elements.
Keywords: scatter plots, the total field, the cylindrical shell piezoelectric transducer, the wave layer
