Flat optics has emerged as a key player in the area of structured light and its applications,
owing to its subwavelength resolution, ease of integration, and compact footprint. Although …

Over the last two decades, the capabilities of metasurfaces in light modulation with
subwavelength thickness have been proven, and metasurfaces are expected to miniaturize …

Nanoscopic chiroptics studies the spin-dependent asymmetric light–matter interactions at
the nanoscale, where the asymmetry can stem from the intrinsic properties of materials …

Symmetric spin–orbit interaction (SOI)‐based approaches apply a practical limit on helicity
multiplexed metaoptics, ie, center symmetric information encoding. Contrarily, asymmetric …

The past few decades have witnessed growing research interest in developing powerful
nanofabrication technologies for three-dimensional (3D) structures and devices to achieve …

Metasurface-based nanoprinting (meta-nanoprinting) has fully demonstrated its advantages
in ultrahigh-density grayscale/color image recording and display. A typical meta …

Electromagnetic (EM) waves have been widely applied in wireless communications, radar
detection, navigation, and target recognition. Radiation and scattering are two common …

Holography has attracted tremendous interest due to its capability of storing both the
amplitude and phase of light field and reproducing vivid three-dimensional scenes …

Metasurfaces have recently been used for multichannel image displays with pixel-size lower
than a wavelength, which indicates the potential application in ultracompact …

Helicity-multiplexed metasurfaces based on symmetric spin–orbit interactions (SOIs) have
practical limits because they cannot provide central-symmetric holographic imaging …
