Overview of OAM Technology in Communications,new capacity in the severely congested spectrum of commercial communication systems. Beams carrying OAM have a helical phase front and a field strength with a singularity along the axial center, which can be used for information transmission, imaging, and particle manipulation. The number of orthogo

Circular Array-Based Radio Frequency Point-to-Point OAM Communications,el to achieve high-spectrum efficiencies. However, there are still big challenges in the multi-mode OAM generation, OAM antenna alignment, and OAM signal reception. To solve these problems, we propose an overall scheme of the line-of-sight multi-carrier and multi-mode OAM (LoS MCMM-OAM) communicatio

Hybrid Mechanical and Electronic Beam Steering for Point-to-Point OAM Communications,mance degradation induced by small antenna misalignment in practical environment. However, in the case of large-angle misalignment, the OAM channel capacity cannot be effectively compensated only by the electronic beam steering. To solve this problem, we propose a hybrid mechanical and electronic be
