Invent invisibility machine
Harry who? No wonder they say that truth is stranger than fantasy! Researchers from Stanford University and the University of Pennsylvania have been working on an invisibility machine appears to be a reality.
The heart of this machine are covered with gold nanowires. Adjusting the level of metal and silicon, can capitalize on the physical properties of nanoscale wires, resulting in an invisibility effect.
“We discovered that a carefully designed gold layer significantly alters the optical response of silicon nanowires,” said Fan Pengyu investigator of this project. This technology of wires covered with gold nano allows light of both materials is canceled each other making it invisible and at the same time, allowing to see outwards. Also claim that it is very effective because it works is a fairly broad spectrum of light from any angle.
Currently engineers are still working on the properties of this material thinking of possible uses to which it may in the future as in sensors, solar panels, solid light, lasers and scale.
