Journal ArticleDOI
Utilization of photon orbital angular momentum in the low-frequency radio domain
Bo Thidé,Holger Then,J. Sjöholm,K. Palmer,Jan Bergman,Tobia Carozzi,Ya. N. Istomin,Nail Ibragimov,Raisa Khamitova +8 more
TL;DR: It is shown numerically that vector antenna arrays can generate radio beams that exhibit spin and orbital angular momentum characteristics similar to those of helical Laguerre-Gauss laser beams in paraxial optics.
Journal ArticleDOI
Orbital Angular Momentum in Radio—A System Study
Siavoush M. Mohammadi,L. K. S. Daldorff,Jan Bergman,Roger Karlsson,Bo Thidé,K. Forozesh,Tobia Carozzi,B. Isham +7 more
TL;DR: In this paper, the authors used vector field-sensing electric and magnetic triaxial antennas to estimate the orbital angular momentum (OAM) of radio beams, assuming ideal (noiseless) conditions and that the beam axis is known.
Journal ArticleDOI
First results of electric field and density observations by Cluster EFW based on initial months of operation

TL;DR: In this paper, the authors present studies of the electric field data from various regions along the CLUS-TER orbit. They all point towards a very high coherence for phenomena recorded on four spacecraft that are sepa- rated by a few hundred kilometers for structures over the whole range of apparent frequencies from 1 mHz to 9 kHz.
Journal ArticleDOI
Parameters characterizing electromagnetic wave polarization
TL;DR: The polarization parameters introduced are formulated in the frequency domain, thereby further generalizing the theory to allow for wide-band electromagnetic waves in contrast to the traditional quasi-monochromatic formulation.
Journal ArticleDOI
Orbital angular momentum in radio: Measurement methods
Siavoush M. Mohammadi,Siavoush M. Mohammadi,L. K. S. Daldorff,Kamyar Forozesh,Bo Thidé,Jan Bergman,B. Isham,Roger Karlsson,Tobia Carozzi +8 more
TL;DR: In this paper, a measurement and approximation methodologies for studying orbital angular momentum (OAM) modes in radio beams, i.e., electromagnetic beam modes having helical phase fronts, are presented.
