OAM multiplexing

(Orbital Angular Momentum multiplexing) Transmitting multiple beams (channels) over the same light frequency in an optical fiber. The channels are differentiated based on their spiral rotation (angular momentum).

Our results indicate that the improved vortex grating has exhibited the wide prospective in OAM multiplexing and channel equalization for optical communication.

Optical Orbital Angular Momentum Demultiplexing and Channel Equalization by Using Equalizing Dammann Vortex Grating

However, investigations about the radio OAM had not been made until Bo Thide's group conducted the radio OAM experiment in [4], which elaborated another perspective of multiplexing, that is, OAM multiplexing for the present communication.

To date, researches about radio OAM mainly lie on the twisted wave antenna design and OAM multiplexing. Uniform circular array (UCA) with each element fed with the same amplitude but successive phase shift was raised in [5] to produce the twisted wavefront.
