A general theorem on the divergence of vortex beams
G. Vallone, G. Parisi, F. Spinello +3
The propagation and divergence properties of beams carrying orbital angular momentum (OAM) play a crucial role in many applications. Here we present a general study on the divergen…
Experimental near field OAM-based communication with circular patch array
Fabio Spinello, Elettra Mari, Matteo Oldoni +6
A short range experimental communication system, based on Orbital Angular Momentum (OAM) multiplexing, is presented. We characterize circular arrays of patch antennas designed to t…
N-tupling the capacity of each polarization state in radio links by using electromagnetic vorticity
Fabrizio Tamburini, Bo Thidé, Elettra Mari +7
The congestion of the radio frequency bands imposes serious limitations on the capacity and capability of modern wireless information infrastructures. One approach to enable freque…
Encoding many channels in the same frequency through radio vorticity: first experimental test
Fabrizio Tamburini, Elettra Mari, Anna Sponselli +5
We have shown experimentally that it is possible to propagate and use the properties of twisted non-monochromatic incoherent radio waves to simultaneously transmit to infinity more…
Radio beam vorticity and orbital angular momentum
Bo Thidé, Fabrizio Tamburini, Elettra Mari +2
It has been known for a century that electromagnetic fields can transport not only energy and linear momentum but also angular momentum. However, it was not until twenty years ago,…
