A Self-Adaptive Reconfigurable Metasurface for Electromagnetic Wave Sensing and Dynamic Reflection Control. [PDF]
Adv Sci (Weinh)Reconfigurable metasurfaces typically require human intervention or complex, resource‐heavy processes. This innovative self‐adaptive metasurface senses an incident wave's direction, adjusting reflection in real‐time using a simple electronics module. It eliminates external controllers, reducing response time, energy consumption, and costs. Applications
