Orbital angular momentum generation in a 60GHz wireless radio channel

We describe transmission of 4-Gbps uncompressed video utilizing a 60-GHz wireless channel with orbital angular momentum (OAM). The laboratory experiments were supported by Matlab simulation; this being utilized to generate holographic masks. Matlab code was further employed to control a printed circuit board (PCB) router drill. Any required shape on, for instance, copper or dielectric plates could be produces. An experimental setup was arranged to validate the transmission performance of 4-Gbps uncompressed video over 60-GHz OAM wireless channel we believe, for the first time. Good agreement was achieved between simulated and measured results. It is concluded that it is practically feasible to send multi-gigabit wireless data over an OAM channel.
