Abstract

The invention discloses an angular momentum generation unit, generator and method. The angular momentum generation unit comprises a dielectric plate; the plurality of metal patches are arranged on the dielectric plate in a mirror image arrangement mode, and the metal patches are arranged in all directions; the plurality of metal patches are connected through the plurality of metal microstrip lines, so that a connection state between each metal patch and other metal patches is formed; by controlling the orientation of the plurality of metal microstrip lines, the connection state or the non-connection state of every two metal patches is realized, the 180-degree phase difference of every two metal patches is achieved, and the independent regulation and control of phases in two polarization directions are realized, so that the wave beams of the orbital angular momentum electromagnetic waves in the orthogonal polarization direction are independently controlled. The angular momentum generating unit provided by the invention is simple in structure, so that the angular momentum generator has broadband and dual-polarization functions, and the two polarizations have the characteristic of high gain, so that the angular momentum generating unit can be applied to dual-channel communication, and high isolation between dual channels is realized.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an angular momentum generating unit, generator and method. Background technique [0002] Orbital angular momentum (vortex electromagnetic wave) A spatial distribution of electromagnetic waves (such as figure 1 As shown), any two integer-order OAM beams have orthogonality, thereby realizing multi-mode multiplexing of OAM, which provides a new dimension to improve channel capacity. Using OAM as an independent channel can greatly improve the communication capacity and spectrum efficiency of wireless communication systems. Potential applications of OAM beams are link backhaul between base stations and near-field communication systems, which are one of the potential technologies in 6G communication. [0003] A metasurface is a structure of periodic units. Such as figure 2 As shown, for the reflective metasurface, the orbital angular momentum is generated by the layout of th...
