Formation of high-quality Airy beam. a, b Amplitude profile in a and phase profile in b at the surface of the LAM for generating the Airy beam. The LAM consists of 80 discrete unit cells (triangles). c, d Simulated pressure fields of Airy beams produced by the APM in c and PM in d. Scale bar, 10 cm. e, f Distributions of pressure amplitude on the dashed lines in c and d. The result for the perfect Airy beam is calculated by Eq. (7), which is displayed for comparison (red lines)
