A single-layer and actively tunable reflective polarization converter is proposed, which is
composed of periodical two-dimensional unit cell of inclined split circular ring filled into by …

Here we demonstrate the two-tier manipulation of holographic information using frequency-
selective metasurfaces. Our results show that these devices can diffract light efficiently at …

In this paper, on the basis of metamaterial, a simply single-layer and tunable reflective
polarization converter has been numerically investigated, which is composed of vanadium …

Metasurfaces have made great progress in the last decade for generating miniature and
integrated optical devices. The optical properties of metasurfaces can be tuned dynamically …

Terahertz chiral sensing and polarization‐multiplexing communication demand
subwavelength devices that dynamically invert polarization helicity. Metasurfaces can …

Metasurfaces have attracted increasing attention due to their unprecedented capabilities of
molding optical fields with exceedingly low losses. Despite significant achievements, most …

Optical metasurfaces have shown great potential for revolutionizing wave plates by enabling
compact footprints and diversified functionalities. However, most metasurface wave plates …

We present the design of an asymmetric metasurface made of germanium antimony
tellurium nanowires that supports quasibound states in the continuum. A fully coupled …

Metalens can achieve more challenging functions especially dynamic regulation than
traditional lens due to its unprecedented ability to manipulate light. In this paper, an …

Metasurfaces have recently gained increasing attention and shown great potential in
replacing bulk optics with ultracompact flat metadevices, owing to their unprecedented …
