Vortex beams are currently drawing a great deal of interest, from fundamental research to several promising applications. While their generation in bulky optical devices limits their use in integrated ...

There are many interesting fluidic phenomena with vortex structures in nature, like tornado, whirlpool and backwash. As a counterpart in wave system, the acoustic vortex can also hold the profile of ...

As a new degree of freedom, the orbital angular momentum of electromagnetic waves exceeds the traditional frequency, phase, and amplitude, and is expected to promote the infinite expansion of channel ...

The high energy radiation that carry the orbit angular momentum has become an extremely important tool to investigate the angular momentum related physics in microworld. But the generation and ...

A research team led by Associate Prof. Wang Anting from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) proposed a method for multidimensional ...
