Secure Transmission of Radio Orbital Angular Momentum Beams Based on the Frequency Diverse Array
IEEE Access, 2021 The circular phased array is one of the main methods to generate radio frequency orbital angular momentum (RF-OAM) beams with high purity and capability of OAM-beams steering, but OAM beams generation and steering are only related to angle, not range ...
