Contactless manipulation of hard-to-reach objects, especially those behind obstacles, is highly demanded in many applications. In this work, auto-focusing acoustic-vortex (A-FAV) tweezers are developed based on-axis-symmetrically arranged and azimuthally phase-coded Half-Bessel (HB) beams, which can self-bend themselves along an arc-shaped trajectory and, hence, circumvent obstacles that located on the beam path. To build such tweezers, active phase control passive binary modulation for a...
