摘要：
In this article, cylindrical and conical conformal arrays are presented to flexibly launch the OAM vortex beams. First, we analyze the characteristics of OAM beams generated by planar annular arrays with different radii. Then characteristics of vortex waves generated by cylindrical and conical arrays with different curvatures are analyzed. Finally, prototypes of cylindrical and conical arrays are fabricated and measured. Experimental results imply that OAM vortex beams can be effectively generated by cylindrical and conical conformal phased arrays, which may provide a reference for electromagnetic vortex communication on the conformal carrier in the future.
