Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a ...

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) has been considered as a new dimension of wireless transmission as well as the intrinsic property of electromagnetic wave. When OAM is applied with the traditional ...
