Fig. 3: 3D FEA simulation of acoustic field morphology and spatial location of the transducer produced at different radii of curvature.
From: Active acoustic field modulation of ultrasonic transducers with flexible composites
a In the xz plane, the theoretical focused zone and simulated focused acoustic field corresponding to different radius of curvature (Rc) on the same x-axis are obtained. b The xy plane distribution of the focused acoustic field corresponding to six different Rc is shown, with a cross-sectional area of 10 × 10 mm2. c Collimation characteristics of the acoustic field: The colored and black dashed lines show the full width at half maximum (FWHM) values of our prepared transducer and the conventional flat transducer at different axis distances. d Lateral resolution of the acoustic field corresponding to different Rc. e Longitudinal resolution of the acoustic field corresponding to different Rc.
