(a) Chip geometry 1 (b) Chip geometry 2 (c) Schema of the multilayer acoustic cavity (d) The suspension of cells particles undergoes the Acoustic Radiation Force (ARF). The cells are first focused in the nodal plane and then, trapped by the transverse component of the ARF. The cavity dimensions are adjusted to have multiple clusters. Example of the levitation and aggregation process: (e) Suspended particles are injected in the cavity. Here is $15 μ m$ diameter polystyrene beads. (f) Axial acoustic radiation forces are dominating and bring the particles in the pressure nodal plane. (g) Therefore, the transverse forces trap particles in a circular monolayer.
