摘要
2011年,瑞典和意大利的科研人员第一次实现了利用传统电磁波和涡旋电磁波在相同频点进行无线通信的实验并取得了成功,被《自然》杂志誉为具有革命性的创新技术。虽然携带轨道角动量的电磁涡旋通信技术目前仍有争议,但科研人员仍致力于涡旋电磁提高通信系统容量的研究。对涡旋电磁通信的基本原理进行了阐释,对该技术的发展历史及现状进行了详细的论述,并展望了电磁涡旋技术的未来发展。
In 2011,researchers from Sweden and Italy firstly and successfully implemented an experiment for wireless communication by transmitting the traditional electromagnetic wave with twisted radio at the same frequency simultaneously,which is praised as a revolutionary technical innovation by Nature.Although the twisted radio wireless communication technology with orbital angular momentum is still controversial,researchers are still committed to using it to significantly increase the capacity of the wireless communication system.The fundamental of twisted radio communication is elaborated,and its history and current status are described and some outlooks on its future are given.
