WebAug 19, 2024 · Phased array ultrasonic testing is widely used to test structures for flaws due to its ability to produce steered and focused beams. The inherent anisotropic nature of some materials, however, leads to skewing and distortion of the phased array beam and consequently measurement errors.
Webexhibits a phase singularity on the beam axis and there-fore vanishes at this point due to destructive interference. Acoustic vortex beams can transfer their angular momen-tum to microscopic and macroscopic solid objects [7–12] and to fluids [13] and exert mechanical torques on them.
