Metasurfaces and Metadevices for Topological Electromagnetic Waves
Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

Dual‐Wavelength Switchable Focusing via a Fabry‐Pérot Resonance‐Enabled Hydrogel Metalens
A hydrogel metalens is demonstrated for dual‐wavelength switchable focusing based on Fabry‐Pérot resonance. Under the low relative humidity, the metalens exclusively focuses light with a resonance wavelength of 470 nm and directly reflects light of other wavelengths.
