Apparatus and method for assembling particles in a working medium to an agglomerate under the effect of acoustic forces

Abstract

The invention relates to an apparatus (100) for assembling particles (1) in a working medium (2) to an agglomerate (3) under the effect of acoustic forces. The apparatus (100) comprises a first acoustic source device (10) configured for emitting a first acoustic holographic interference field (11) along a first direction (12) and a second acoustic source device (20) configured for emitting a second acoustic holographic interference field (21) along a second direction (22). Further, the first acoustic source device (10) and the second acoustic source device (20) are arranged such that the first acoustic holographic interference field (11) and the second acoustic holographic interference field (21) are superimposed with each other in an assembling portion (101) to form an acoustic pressure field, which defines a shape of the agglomerate (3). Further, the first acoustic source device (10) and the second acoustic source device (20) are arranged such that the first direction (12) and second direction (22) are tilted relative to each other. Furthermore, a method for assembling particles (1) in a working medium (2) to an agglomerate (3) under the effect of acoustic forces is described.
