Acoustic Fields of a Piezoceramic Cylindrical Electroelastic Multimode Converter with a Matching Layer

The problem on the reception of sound in a circular cylindrical multimode converter layer with electroelastic properties of piezoelectric membrane and the transition layer in the “through” setting is considered. Features of the formation of acoustic fields in the working medium in the form of interference patterns and angular distributions of the pressure of a complete receiving cylindrical converter are investigated. The angular characteristics of the total-field distributions at different distances from the surface of a multimode converter are investigated for different types of electrodes when a layer of quarter-wave and half-wave thickness is used.
