Lightweight, miniaturized optical imaging systems are vastly anticipated in these fields of
aerospace exploration, industrial vision, consumer electronics, and medical imaging …

All-dielectric metasurfaces have been intensively researched as a low-loss, flat-optics
platform for the advanced manipulation of electromagnetic wave propagation. Among the …

Symmetry-protected bound states in the continuum (SP-BICs) are one of the most intensively
studied BICs. Typically, SP-BICs must be converted into quasi-BICs (QBICs) by breaking the …

Dispersion is one of the key performances of optical systems. As a man‐made device,
metasurface is a notable alternative for dispersion manipulation and has been developed …

The field of flat optics that uses nanostructured, so‐called metasurfaces, has seen
remarkable progress over the last decade. Chalcogenide phase‐change materials (PCMs) …

Metasurfaces exhibit excellent performance in the regulation of optical field parameters,
such as phase, amplitude, and polarization, by using nanounit structures. The characteristics …

Metalens, a metasurface with a focusing phase, has been the focus of research due to its
immense potential for use in imaging and display technology. Traditional lens and optical …
