Description
technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a polarization mode composite agile orbital angular momentum antenna. Background technique [0002] Orbital angular momentum (OAM) electromagnetic waves carry orbital angular momentum because of their helical phase factor, and their topological charges, also known as modal numbers, become a new type of multiplexing physical dimension. Orbital angular momentum technology was first discovered and applied in optics. Its special phase structure and polarization structure are widely used in the fields of optical communication, particle manipulation and optical imaging. Manipulation, trapping and absorption, etc. and the unique focusing characteristics of vector orbital angular momentum beams enable laser processing and material processing, etc. [0003] After the orbital angular momentum electromagnetic wave topological charge (modal) is confirmed by experi...
