The acoustic pressure fields under either with or without the acoustic lens. Acoustic field propagations without (top) and with (bottom) the concave-shaped acoustic lens. (a) Schematic of the measured domain without the lens. (b) Simulated and (c) measured results of the pressure field without the lens. (d) Schematic of the measured domain with the lens. (e) Simulated and (f) measured results of the pressure field with the lens. The mean value distributions of (g) simulated and (h) measured acoustic pressure along one Z-axis at each X position without the lens. The mean value distributions of (i) simulated and (j) measured acoustic pressure along one Z-axis at each X position with the lens. The dotted box represents the area of interest (AOI).
