Generation of spatiotemporal acoustic vortices with arbitrarily oriented orbital angular momentum
Shuai Liu, Hao Ge, Xiang-Yuan Xu +4
Despite extensive exploration of acoustic vortices carrying orbital angular momentum (OAM), the generation of acoustic vortices with OAM orientations beyond the conventional longit…
