Important results from the project
The project addresses the challenges posed by extensive glass surfaces in modern architecture and automotive industries, which typically hinder energy efficiency and climate control. We developed coding metasurfaces a novel approach utilizing micro- and nano-structured layers of dielectric and semiconductor materials. These metasurfaces are designed to be fully transparent, transmit RF signals, and diffuse reflect near-IR/IR solar radiation, while also offering real-time tunability to switch between reflecting and absorbing solar energy.
Expected long term effects
The project on solar metaglass utilizing coding metasurfaces has yielded promising results with prototypes. Looking forward, these coding metasurfaces hold immense potential to revolutionize energy-efficient building and automotive applications. The anticipated impacts include substantial reductions in energy consumption, improved indoor comfort, and enhanced environmental sustainability across diverse geographical regions.
