Abstract

Previously, the design of negative acoustic radiation force was mostly based on beam control. Realizing the negative acoustic radiation force through the design of the manipulated structure is a new and valuable idea. In this paper, a resonant adhesion structure capable of generating negative acoustic radiation force is designed. Finite element simulations are carried out to verify the feasibility of this negative acoustic radiation force scheme. The variation law of the acoustic radiation force with the frequency of the incident acoustic beam and various parameters of the resonant adhesion structure is explored and explained in detail. The proposal of this design lays a foundation for the realization of the negative acoustic radiation force, which has broad application prospects in the fields of medicine and life sciences.
