Abstract

The invention discloses an angular momentum generating unit, generator and method, comprising: a medium plate; Patch; multiple metal microstrip lines, and multiple metal patches are connected by multiple metal microstrip lines to form the connection state between each metal patch and other metal patches; by controlling the connection of multiple metal microstrip lines Orientation, realize the connection state or non-connection state of every two metal patches, achieve a phase difference of 180° between every two metal patches, and realize the independent adjustment of the phase in the two polarization directions, so as to control the orthogonal polarization direction. Beam-independent control of the orbital angular momentum of electromagnetic waves. The angular momentum generating unit proposed by the present invention has a simple structure, so that the angular momentum generator has the function of broadband and dual polarization, and both polarizations have the characteristics of high gain, so that it can be applied to the communication of dual channels, and realizes dual-polarization. High isolation between channels.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to an angular momentum generating unit, a generator and a method. Background technique [0002] Orbital Angular Momentum (vortex electromagnetic wave) A spatial distribution of electromagnetic waves (eg figure 1 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 spectral efficiency of wireless communication systems. The potential applications of OAM beams are in systems such as link backhaul between base stations and near-field communication, which is one of the potential technologies in 6G communication. [0003] A metasurface is a structure of periodic units. like figure 2 As shown, for a reflective metasurface, orbital angular momentum is generated by p...
