| Abstract: | Sound fields generated by transducers with sphere cone acoustic lens are studied through numerical calculations and experiments.The results indicate:a narrow sound beam over a longer axial range can be obtained by sphere cone acoustic lens,and sound field characteristics are greatly affected by shape parameters of the curved surface |
| Keywords: | focusing lens acoustic field |
