Effect of the Acoustic Field Geometric Parameters on Planar Array Acoustic Levitator

Acoustic contactless manipulation technique that is capable of transporting and manipulating of small particles is highly attractive in studying of many physical phenomena and biochemical processes. The finite element method is used to study the effect of the acoustic field geometric parameters on the acoustic levitator consisting of the transducer planar array and a reflector. The optimal acoustic chamber height and the distances between the array elements are determined through the numerical simulation. The analytical results provide the geometry parameters that can be used in optimizing acoustic chamber for particles transportation.
