TL;DR: A multifocus optical vortex metalens, with enhanced signal-to-noise ratio, is presented, which focuses three longitudinal vortices with distinct topological charges at different focal planes for circularly polarized light in a compact device.
Journal ArticleDOI
Advances in Full Control of Electromagnetic Waves with Metasurfaces
TL;DR: In this paper, the latest advances in full control of electromagnetic waves with metasurfaces are briefly reviewed from a functionality perspective, and several promising approaches are suggested to extend the applications of metamaterials.

TL;DR: In this paper, a transmission-type metahologram achieving images in three colors, free from high-order diffraction and twin-image issues, with 8-level modulation of geometric phase by controlling photon spin via precisely patterned Si nanostructures with varying orientations.
Journal ArticleDOI
Noninterleaved Metasurface for (26-1) Spin- and Wavelength-Encoded Holograms.
