Keywords: bottle beams; plasmonic metalens; surface plasmon polariton EN bottle beams plasmonic metalens surface plasmon polariton 1969 1976 8 05/12/22 20220401 NES 220401 1 Introduction Surface plasmon polariton (SPP), with the capability of breaking through the traditional optical diffraction limit [[1], [2]], shows advantages of nanoscale spatial resolution and tremendous localized electromagnetic field enhancement [[3]]. DIAGRAM: Figure 3: Generation of SPP bottle beam by proposed metalens.(a) Schematic diagram of the principle of synthesizing SPP bottle beam. Based on this principle, we designed and generated a series of SPP fields, including S- and W-shaped SPP focal fields and SPP bottle beams, and the effectiveness of the proposed method is verified experimentally.
