This contribution presents a new approach concerning the acoustic 3D-manipulation of particles in a liquid filled volume. Based on simulation studies and a physical model, the realization of acoustophoresis using the acoustic radiation force (ARF) on particles in a liquid-filled vessel is discussed. The discrete local acoustic pressure field, that is required for the acoustophoresis, is generated by a time reversal mirror consisting of 24 piezoceramic transducers.
