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 ...

Transverse flux machines (TFMs) represent a significant evolution in electric machine design, notable for their unique magnetic flux orientation that is perpendicular to the rotor axis. This ...

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 ...
