Coherent detection of orbital angular momentum in radio
L. K. S. Daldorff, S. M. Mohammadi, J. E. S. Bergman +4
The angular momentum propagated by a beam of radiation has two contributions: spin angular momentum (SAM) and orbital angular momentum (OAM). SAM corresponds to wave polarisation,…
Photon orbital angular momentum in a plasma vortex
J. T. Mendonça, B. Thidé, J. E. S. Bergman +4
We study theoretically the exchange of angular momentum between a photon beam and a plasma vortex, and demonstrate the possible excitation of photon angular momentum states in a pl…
Detecting orbital angular momentum in radio signals
H. Then, B. Thidé, J. T. Mendonça +5
Electromagnetic waves with an azimuthal phase shift are known to have a well defined orbital angular momentum. Different methods that allow for the detection of the angular momentu…
Conservation Laws in Generalized Riemann-Silberstein Electrodynamics
Jan E. S. Bergman, Siavoush M. Mohammadi, Lars K. S. Daldorff +4
Starting from positive and negative helicity Maxwell equations expressed in Riemann-Silberstein vectors, we derive the ten usual and ten additional Poincar{é} invariants, the latte…
