Acoustic vortices in inhomogeneous media
We observe a series of unstable and dynamic behaviors of acoustic vortices propagating in stratified inhomogeneous media. These behaviors include bending, stretching, distorting, focusing, and untwisting of the vortices, migration of singular points, and reversal of energy flux and angular momentum....
