Patterns of the efficiency of sound emission by an antenna array consisting of multimode cylindrical electroelastic transducers
Main Article Content
Abstract
In the conditions of diffraction interaction of circular cylindrical radiating electroelastic transducer with cutting electrodes the acoustic unloading situation and decrease in efficiency of transducer radiation at the expense of an active component reduction of radiation impedance that is caused by interaction on an acoustic field is considered. Positive influence of multimode and coherence of fluctuations modes of system transducer on effect unloading, almost excluding selection of energy by the transducer from the outside is shown.
