A method to efficiently generate orbital angular momentum (OAM) vortex beam is proposed by introducing generalized coding metasurface (CM). Firstly, a linearly polarized (LP) cross-polarization transmission unit cell is employed as the coding element. Then, the generalized CM composed of sectorial coding elements can be considered as a bridge linking mode number of OAM and beam divergence with coding sequences. Different mode numbers OAM is generated by CMs with different coding sequences under y-polarized wave normal incidence. Both theoretical analysis and simulated results reveal that the proposed CM can achieve flexible control of the OAM vortex beam.
