A Review of Orbital Angular Momentum Vortex Beams Generation: From Traditional Methods to Metasurfaces
In this paper, we review the generation of vortex beams carrying orbital angular momentum in the microwave domain. We firstly present the theory of Laguerre−Gaussian beams where it is demonstrated that they carry such type of momentum. We further provide an overview of the classical method...
