Single beam selective acoustical tweezers: from acoustical vortices to focused beams.

ORAL · Invited

Abstract

Single beam acoustical tweezers open some tremendous perspectives for the precise selective manipulation, assembly and mechanical properties testing of microscopic objects, cells and microorganisms. In this presentation we will first review the 2D and 3D trapping capabilities of acoustical vortices (some helical wave spinning around a phase singularity) and focused beam. Then we will discuss our latest experimental developments on ultra-high frequency microparticles manipulation with nanoNewton forces and 3D manipulation of particles with frequency induced axial displacement of the trapped object. Finally, we will introduce a new mixed finite element/angular spectrum code, which enables to compute precisely the field generated by active holographic transducers.
