(a) Spatial phase profile in the x-axis for a deflected acoustic bottle-beam and (b) the acoustic field distribution of the deflected acoustic bottle-beam through the AM. Here, the incident angles φ1 = φ2 = 0°. (c) The intensity contrast \({|p/{p}_{0}|}^{2}\) profile on the line “I” in (b). (d) Spatial phase profile in the x-axis for the case of \({\phi }_{1}={\phi }_{2}={25}^{\circ }\) and (e) the corresponding acoustic field distribution of the acoustic bottle-beam. (f) The intensity contrast \({|p/{p}_{0}|}^{2}\) profile on the line “I” in (e). (g) Spatial phase profile in the x-axis for the case of (\({\phi }_{1}={\phi }_{2}={45}^{\circ }\)) and (h) the corresponding acoustic field distribution of the acoustic bottle-beam. (i) The intensity contrast \({|p/{p}_{0}|}^{2}\) profile on the line “I” in (h). The green dashed lines indicate the theoretical propagation trajectories.
