Acoustic spin Hall-like effect in hyperbolic metamaterials controlled by the helical wave
Abstract Because of the spin-less nature of sound, acoustic helical wave with different helical directions can be taken as a “spin-like” degree of freedom. In this Letter, we examine the pseudospin-orbit coupling effect in acoustics when an acoustic helical wave emitter interacts with the acoustic h...
