Acoustic radiation force(ARF),as an important particle manipulation method,has been extensively studied in recent years.With the introduction of the concept of"acoustic tweezers",negative acoustic radiation has become a research hotspot.In this paper,a scheme of realizing negative ARF based on the multiple-layered spherical structure design is proposed.The specific structure and design idea are presented.Detailed theoretical calculation analysis is carried out.Numerical simulations have been performed to verify the correctness of this prediction.The conjecture that the suppression of backscattering can achieve negative ARF is verified concretely,which greatly expands the application prospect and design ideas of the ARF.This work has laid a theoretical foundation for realizing precise control of the structure.
