Dynamic angular tuning of thermal emission is a problem in the field of thermal metasurfaces. Here, the authors make a thermal emission device using electrostatic gates, opening an avenue for radiative heat management and mid-infrared communication.

Here, the authors fabricate a metasurface with nanometre-sized plasmonic hotspots that interact coherently with WS₂ excitons, achieving ultrastrong exciton-plasmon coupling.

The researchers introduce an all-silicon optical PUF that enhances IoT device security through CMOS-compatible fabrication, showcasing five unique optical responses per pixel for advanced authentication and high information entropy.

The researchers showcase a flexible meta-sensor array based on classical Mie resonance, enabling precise detection of in-plane strain direction and magnitude using dynamically transmitted terahertz (THz) signals. The sensor array holds immense promise for the real-life applications as it possesses high sensor density and has a very large size up to (110 ×130 mm²).
