Abstract
|In this paper, wideband and high efficiency millimeter-wave circular Airy orbital angular momentum (OAM) beams, which have desired multiplexing OAM modes, directions, and beam numbers, are generated by the proposed three metal layer transmission metasurfaces (TMSs) with size 12 (cid:21) 0 (cid:2) 12 (cid:21) 0 based on the Airy-OAM phase superposition method. The measured results indicate non-diffracting propagation distance 31 (cid:21) 0 , autofocusing property, high aperture efficiency 13.1%, and wideband 16.8% (28 GHz{33 GHz). The design method can be used for circular Airy OAM beam generation in point-to-point, point-to-multipoint wireless power transmission (WPT), and OAM mode multiplexing communication systems.
