Orbital angular momentum (OAM) multiplexing for a wireless backhaul communication system: Ultimate capacity analysis of OAM channels

Abstract

A novel approach for establishing a wireless communication link using orbital angular momentum (OAM) beams in E-band frequency for 5G communication is studied. OAM beams have been generated by converting the high-power Gaussian beam generated from a vacuum tube device into Laguerre-Gaussian (LG) beams using a meta-material structure to transmit the information signal to a distance of 2 meters. Objective of the system is to prepare a in laboratory experimental setup to demonstrate the capability of OAM communication in terms of channel capacity and degree of freedom.
