Study on the Formation Method of OAM Vortex Electromagnetic Wave

随着现代无线通信技术的迅猛发展,不断增加的通信业务使得有限的频谱资源越发紧缺。携带多模式轨道角动量的涡旋电磁波应用于通信领域,以提高频谱利用率,增加信道容量。基于此,本文概述了涡旋电磁波的概念,详细列举了目前能产生涡旋电磁波的各种天线结构,并简单阐述其工作原理。为设计尽可能多模态的轨道角动量天线奠定基础。

With the rapid development of modern wireless communication technology,the increasing communication services make the limited spectrum resources more and more scarce.Vortex electromagnetic waves carrying multi-mode orbital angular momentum are used in communication to improve spectral utilization and increase channel capacity.Based on this,this paper summarizes the concept of vortex electromagnetic wave,lists various antenna structures that can generate vortex electromagnetic wave in detail,and briefly describes their working principle.It lays the foundation for designing orbital angular momentum antennas with as many modes as possible.
