Programmable Micro-Mirrors for Real-Time Emissivity Control and Switching (Case No. 2025-254)

Summary: UCLA researchers in the Department of Mechanical and Aerospace Engineering have developed a fast-switching, MEMS-based thermal metasurface that enables real-time infrared emissivity modulation via high-contrast, broadband radiative control. Background: Dynamic emissive thermal devices offer active control over infrared (IR) radiation....
