Revolutionary Cloud Material Bends Light Around Corners

Scientists at the University of Glasgow have developed a groundbreaking method to bend light around corners, inspired by the way clouds scatter sunlight. This innovative technique may revolutionize domains such as medical imaging, electronics cooling, and even the design of nuclear reactors.

Lead researcher Daniele Faccio and his team expressed their surprise that this phenomenon had not been identified earlier. They discovered that, similar to clouds and other white materials, when light hits the surface, it scatters in numerous directions, limiting penetration and resulting in reflection.

To simulate this effect, the researchers 3D printed objects from opaque white materials while embedding transparent tunnels. Shining light into these objects causes it to enter the tunnels and scatter in a controlled manner, enhancing transmission significantly compared to solid blocks.

While this method does not match the efficiency of traditional fibre optics, which reflect light internally, it offers a simpler and more cost-effective alternative. Furthermore, it holds potential for various engineering applications, including the utilization of translucent materials in medical imaging and cooling systems.

“It wasn’t obvious that this would work at all,” Faccio remarked, highlighting the simplicity yet powerful application of this discovery.
