Abstract

As novel planar structures, the metasurfaces exhibit the unprecedented capability to manipulate the amplitude, phase, and polarization of electromagnetic waves. Therefore, metasurface is designed to apply to metalens, holography, nanoprinting display, encryption, and so on. It is very interesting and meaningful work to integrate bifocal metalens and nanoprinting images into a single metasurface. A method is proposed to combine propagation phase and geometric phase, as well as Malus's law to realize the function of the bifocal metalens and clear nanoprinting display in the near field which can be observed at a certain polarization. This original design expands the functional integration of metasurface and improves applications in image displays, optical storage, augmented reality, virtual reality, and many other related fields.
