TL;DR: It is shown that the optical catenary can serve as a unique building block of metasurfaces to produce continuous and linear phase shift covering [0, 2π], a mission that is extremely difficult if not impossible for state-of-the-art technology.

TL;DR: In this paper, an off-axis illumination method was developed to overcome the cross-talk limitation and achieve multicolor meta-holography with a single type of plasmonic pixel.

TL;DR: In this article, a monolayer metasurface is proposed to simultaneously realize circular asymmetric transmission (AT) and wavefront shaping based on asymmetric spin-orbit interactions, achieving an extinction ratio of ≈10:1 and an AT parameter of ≆0.69 at 9.6 µm.

TL;DR: It is demonstrated that broadband coherent perfect absorber (CPA) can be achieved by heavily doping an ultrathin silicon film and two distinct perfect absorption regimes are derived with extremely broad and moderately narrow bandwidth under symmetrical coherent illumination.

TL;DR: A planar chiral antenna array is experimentally demonstrated to produce optical vortex from a circularly polarized light and has the ability to focus the incident light into point, which greatly increases the power intensity of the generated optical vortex.
