Hiding in Plain Sight – New Invisible Materials
August 16th 2008 06:22
The fabrication of two new materials which are able to manipulate light could pave the way for the development of cloaking technology. They each work on the optical band of the spectrum and have to potential to hide objects in plain sight.
They were created at the University of California, Berkeley lab by engineer Xiang Zhang and Steve Cummer of Duke University. They say that the materials are able to bend light but more engineering is still required in order to direct those rays in the right direction. "This is getting close to actual nanoscale devices," Cummer says of the Berkeley prism.
In the short term, the two Berkeley materials are likely to be useful in telecommunications and microscopy. Or even be integrated into super-light microscopes. Many other possibilities are also being considered.
The challenge for researchers is now to scale-up the project so that small and then large objects might be easily concealed, but they also warn that cloaks for moving objects could yet be a long way off.
