Realizing caustics in acoustic fields
journal contribution
posted on 2023-06-09, 22:46 authored by Samaneh Moeini, Gianluca MemoliGianluca Memoli, Sriram SubramanianWe present a method to realise a wide class of caustics in acoustic fields created by a set of phase holograms realized with metasurfaces. Given the desired caustic shape, we discuss how to identify the phase distribution along the metasurfaces and describe the calculations needed for determining the pressure field in the vicinity of the caustic. The results of this work can be used in realising acoustic traps controllable with acoustic metamaterials.
