SYSTEM FOR TRANSMISSION AND/OR RECEPTION OF SIGNALS HAVING ELECTROMAGNETIC MODES WITH ORBITAL ANGULAR MOMENTUM, AND DEVICE AND METHOD THEREOF

摘要

A system is described, along with the related device and method, for transmission and/or reception of signals having electromagnetic modes with orbital angular momentum (OAM), wherein said device is adapted to receive, at its input, electromagnetic signals from at least one transmitter, and is configured to apply a discrete Fourier transform to the electromagnetic signals in order to generate the signals having electromagnetic modes with orbital angular momentum.
