Asymmetric Transmission and Diffraction Engineering in Ultrathin media via Coupled Metasurfaces
Grating‐insulator‐grating coupled crosstalking metasurfaces hosted on a silicon nitride membrane platform for asymmetric control of the diffraction pattern and asymmetric transmission. It is shown that exploiting the interferences of higher diffraction orders between the two metasurfaces and engineering the resulting modes enables AT in such ...

High‐Chroma, High‐Contrast Tunable Color Coatings Using Sb2S3 in a Metal‐Dielectric Stack
A novel tunable color coating design is presented, using the phase‐change material Sb2S3 in a Fabry–Perot cavity. The resulting coatings yield bright, attractive colors, and display a significant color change when annealed using a hotplate or a laser. This demonstrates that Sb2S3 is a promising candidate for use in tunable color coatings.
