Description
Summary:A controllable multi-sector array beam is proposed in this Letter. The beam can be generated with the metalens phase. The intensity distribution of the beam at the focal plane is analyzed in detail. The influence of the parameters a and l on the focal field distribution is discussed. The theoretical and experimental results demonstrate that the parameter a affects the size of the beam, and the additional factor l can adjust the sub-region number of the multi-sector array beams. The beam shows potential for use in optical manipulation and image transmission.
