A research team has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does. The findings shattered ...
It has been known for more than a century, since the seminal works by J.H. Poynting 1, that light carries momentum and angular momentum (AM) 2,3. These are the main dynamical properties of ...
Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely ...
