Abstract :
The single-cycle wavefront propagated into water by PVF2-film transducers is visualised by a stroboscopic Schlieren system, and is compared with that from conventional piezoceramic probes. For the film transducers, no edge waves can be observed, nor are they apparent in the transmit-receive impulse response.
