Abstract :
This paper describes the design and the development of transducer arrays fabricated from miniature piezoceramic hollow spheres, the BBs. After the presentation of the fabrication procedure of the transducers, it presents the numerical tools used to model 2×2 and 4×4 transducer arrays in water. Numerical calculations give good agreement with the experimental results and provide physical insight for understanding the acoustic observations.
