英文摘要	This paper presents ultrathin multi-focusing metalenses that can produce several independent focusing spots, useful in imaging for light flow redistribution, even asymmetrical into many focal spots. The proposed design includes quadrangular frustum pyramids serving as individually tuned nanoantennas; their structure can be modified, facilitating wave-phase retardation tuning. Combining the propagation phase control with the PancharatnamBerry phase principle allows the screening of various cell structures. The specific design of the unit-cell structures makes the metalenses capable of single- and double-focusing at the required focal length. Thus, this metalens design might help in developing precision optics for micro-object manipulation.
