摘要

本文基于Airy-OAM相位叠加法，提出了尺寸为12 (cid:21) 0 (cid:2) 12 (cid:21) 0的三个金属层传输超表面(tms)，生成了具有理想复用OAM模式、方向和波束数的宽带高效毫米波圆形Airy轨道角动量(OAM)波束。测量结果表明:无衍射传播距离31 (cid:21) 0，具有自动对焦性能，高孔径效率13.1%，宽带16.8% (28 GHz{33 GHz)。该设计方法可用于点对点、点对多点无线电力传输(WPT)和OAM模式复用通信系统中的圆形Airy OAM波束生成。

MILLIMETER-WAVE WIDEBAND HIGH EFFECIENCY CIRCULAR AIRY OAM MULTIBEAMS WITH MULTIPLEXING OAM MODES BASED ON TRANSMISSION METASURFACES

|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.
