Non-paraxial accelerating acoustic beam (f = 4 kHz).
(a) Spatial phase profile along the x direction for a circular trajectory with a radius of 2 m. (b) Simulated sound field distribution (dB) for the circular trajectory with a radius of 2 m. (c) Non-paraxial accelerating beam (dB) with order β = 100.
