Acoustic propagation of a vortex beam in typical Arctic sound environments
Chengjun Wang, Liwei Chen, Tengjiao He +2
This study investigates the propagation of acoustic vortex beams carrying orbital angular momentum (OAM) in the Arctic underwater environments including the half-channel and the do…
Intercoupling of bulk acoustic streaming and acoustothermal effect: A high-frequency focused beam example
Shiyu Li, Zhixiong Gong
High-frequency focused acoustic beams are promising for selective trapping of cells in fluids, but the related acoustic absorption may generate large acoustothermal effect which co…
Competition between acoustic radiation force and streaming-induced drag force in focused beams for 3D cell trapping
Shiyu Li, Zhixiong Gong
The ability to trap a single cell or microparticle in three dimensions is important for biomedical and microfluidic applications. Single-beam acoustic tweezers based on focused wav…
Experimental demonstration for precisely tuning the focal length of finite-aperture focused beams and vortex
Shiyu Li, Yicheng Feng, Weiwei Cui +1
High-frequency focused ultrasound is widely used in biomedical applications such as high-resolution imaging, neuromodulation, particle manipulation, and so on. However, dynamic tun…
