Abstract
It is shown that the spatial distribution of the acoustic field of a broadband transducer may influence the degree of distortion of ultrasonic signals. The principle for forming a uniform acoustic-field distribution within the directivity characteristic of a low-frequency broadband transducer based on the chosen topology of a mosaic transducer is proposed. The comparative spatiotemporal characteristics of mosaic broadband transducers with optimized and nonoptimized mosaic topologies are obtained as a result of simulation. It is shown that for an optimized topology uniform field distributions can be obtained in both far- and near-field zones of the broadband transducers.
