摘要：
In this paper, a planar metasurface operating in microwave region to generate Bessel beam carrying orbital angular momentum (OAM) is proposed. The beam generator is realized by utilizing the abrupt phase changes at the interface of the metasurface, instead of the gradual phase differences in the optical lenses. The proposed planar metasurfaces are designed and simulated respectively, and the results show that the desired beams can be generated efficiently by using a compact planar 2-D structure.
