We investigated the acoustic radiation force (ARF) acting on a spherical brass particle near a stiff plate without openings but patterned with periodic stubs.Simulation results showed that the particle near plate which the distance is less than 0.5d can be pulled backward when external acoustic waves impacted into the system.And the ARF will decrease when the size of the particle increases.We also demonstrated that the dramatic pulling force originates from the collective excitation of nonleaky flexural lamb modes in the periodically structured solid plate.

Key words: periodic grid structure, stiff plate, spherical particles, sound capture
