Parameters of the developed shocks in the focal waveforms produced by the transducers with different F-numbers. The waveforms are shown in Fig. 6(c). t− and t+ are the durations of the rarefactional and compressional phases of the focal waveform, correspondingly. p+ and p− are peak positive and negative pressures in the waveform.
| F-number | Source voltage, V | p−, MPa | t−/t+ | p+/p− |
|---|---|---|---|---|
| 0.77 | 100 | 17 | 1.33 | 5.6 |
| 1.02 | 70 | 9 | 1.4 | 6.5 |
| 1.52 | 55 | 5 | 1.4 | 5.2 |
