Be it water, light or sound: waves usually propagate in the same way forwards as in the backward direction. As a consequence, when we are speaking to someone standing some distance away from us, that ...

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...
