End-to-end inverse design for programmable acoustic tweezers with simultaneous force and torque control by metasurfaces.

ABSTRACT: Acoustic tweezers leverage acoustic radiation forces for noncontact manipulation. One of the core bottlenecks in multidimensional manipulation is the lack of a systematic design methodology, which prevents the generation of an acoustic field that simultaneously meets the collaborative control requirements of multi-degree-of-freedom forces and torques, making it difficult to achieve precise control under conditions of stable suspension, high-frequency rotation, and complex spatial constraints. To address this challenge, we develop an end-to-end inverse design methodology for acoustic tweezers based on coding metasurfaces, establishing a dual-objective, dual-scale optimization paradigm. At the microscale, the phase modulation and transmission efficiency are co-optimized through coupled physi
