Ultra‐broadband OAM generator of high‐efficiency, high‐purity vortex electromagnetic waves based on an ultrathin reflective Pancharatnam–Berry metasurface for the microwave band
Abstract In this paper, a new arc‐shaped meta‐atom like a fishbone controlled by Pancharatnam–Berry (PB) phase is designed for a microwave band, which can yield a high‐purity vortex electromagnetic (EM) waves ranged from 10.63 to 26.86 GHz (relative bandwidth of 86.6%) with an efficiency of more tha...
