Figure 3: Self-reconstruction of self-bending acoustic beams.
From: Generation of acoustic self-bending and bottle beams by phase engineering
Numerical simulation (a) and experimental measurement (b) demonstrate that the synthesized self-bending acoustic beam propagating along a cubic Bézier curve (white dashed line) is capable of reconstructing its beam profile after the main lobe is blocked by a steel rod (grey disk) in the beam path. The grey dashed arrow in a indicates the proceeding direction of the acoustic beam. Scale bar, 0.1 m. a.u., arbitrary unit.
