Vortex electromagnetic wave radar (涡旋电磁波雷达)

Vortex electromagnetic waves are a type of electromagnetic wave that carries orbital angular momentum. These waves have spiral phase wavefronts and infinite modes, which can introduce new degrees of freedom to communication and microwave imaging. Some publications are listed below.
