Schematic of a THz communication link using OAM multiplexing. (a) Propagation of an OAM beam through turbulence leads to the distortion of its phasefront. At the receiver side, such a beam evolves to a beam with both distorted amplitude and phase profiles. (b,c) A receiver with limited aperture size and misalignment could further degrade the system performance. Tx transmitter, Rx receiver.
