A novel multi-focusing metalens in the longitudinal direction has been proposed and investigated based on equal optical path principle, which is independent incident polarizations can be suitable for both of linear circular polarization incidences simultaneously. Here, three designing principles: partitioned mode, radial alternating mode angular have firstly constructing different types metalenses. The performances designed metalenses methods also analyzed detail, intensity ratio focusing spots tuned easily by modulating numbers relative type nanoantennas, significant micro-manipulating optics multi-imaging technology integrated optics.
