“…Even an ideal piston sound source generates side lobes, but these are small in the case of the partial electrode transducer. Since the side lobe is one factor that determines the directivity of the transducer [6,9,11], it is important to consider the directivity of a partial electrode transducer in designing the ultrasonic probe.…”

“…For this reason, vibration of the transducer is not like piston source and vibration velocity is distributed on the surface of transducer [2,3,4,5]. As a result, the sound field is not always generated as represented by Rayleigh integral [6,7,8,9,10,11,12].…”

“…The most tentative method for observing a sound field of ultrasonic waves is to scan a miniature hydrophone in a field such as water [1]. The resulting output is directly proportional to the sound pressure of the ultrasonic wave.…”
