Generation of Non-aliased Two-dimensional Acoustic Vortex with Enclosed Metasurface
Two-dimensional (2D) acoustic vortex allows new physics and applications different from three-dimensional counterparts, yet existing mechanisms usually have to rely on active array composed of transducers which may result in complexity, high cost and, in particular, undesired spatial aliasing effect...
