Abstract: Orbital angular momentum (OAM) radar is a new type of radar that can provide azimuth information about targets in the field of detection and imaging. However, previous OAM radar systems have ...
Abstract: In this paper, we proposed a reconfigurable metasurface that can generate multi-mode OAM vortex beams with high purity in the X-band. The metasurface has two-dimensional reconfigurable ...
