Recent findings confirm the conservation of orbital angular momentum in single-photon interactions, reinforcing fundamental ...

This letter presents an effective optimization synthesis approach for orbital angular momentum (OAM) beams with low sidelobe and high mode purity through antenna array complex excitation optimization.

Orbital angular momentum (OAM) mode multiplexing has the potential to achieve high spectrum-efficiency communications at the same time and frequency by using orthogonal mode resource. However, the ...

Imagine standing in a field and witnessing what appears to be a tornado made entirely of fire, spinning violently through the ...
