The orbital angular momentum (OAM) of electromagnetic waves ... The helical modes are characterized by a topological charge. OAM beams with distinct topological charges are mutually orthogonal ...

A team of scientists has been able to reveal, for the first time, the dynamics of the orbital angular momentum of plasmons ... However, the size of these beams cannot be smaller than one ...

Orbital Angular Momentum (OAM), can be controlled. This newfound control of neutron OAM states means that researchers can now use neutron OAM beams to see inside materials that optical ...

Bessel beams look quite different from the usual Gaussian light beams found ... free propagation and the ability to carry orbital angular momentum (OAM). This family of beams—also known as ...

Orbital angular momentum has the potential to transfer, manipulate and store information. They are made from the orbital angular momentum of electrons orbiting their atomic nucleus – and the study of ...

Researchers discovered in 1992 that a beam of light could have orbital angular momentum, meaning that the beam twists as it propagates forward, with each photon circling around the centre of the beam.

Among various solutions, mode-division multiplexing (MDM) has emerged as a crucial technique, utilizing spatial modes like orbital angular momentum (OAM) to enhance communication capacity.

The latest twist is based on the Orbital Angular Momentum of light or OAM, which allows a beam of a particular color – or wavelength – to be twisted into a corkscrew shape to increase the ...
