If you a big fan of Harry Potter series, then you must be very familiar with his invisibility cloak, where he uses it to hide himself from being spotted by anyone else (Although Alastor Moody can easily penetrate it by using the magical charmed eye!)
You might think that It is impossible to develop the invisibility cloak, as this stuff only exist in the magical world! Guess what, the scientists from Duke University explained how to hide objects from a dramatically extended range of wave lengths, and they informed that the invisibility cloaks for visible light could be done within the next six months!
David Smith, the professor of Duke University said that the invisibility cloak will be accomplished within six months of time. This invisibility cloak has its own name, The Duke Cloak!
According to the scientists from Duke University, if you want to manipulate light, the microscopic surface of a material must be smaller than the wave lengths of light that being used. If not, the invisibility cloak won’t work as it did.
However, there’s still a limitation for this invisibility cloak, where it only works in two dimensions. The scientists have mentioned that they will gain up the researches to transform it into an invisibility cloak that can be used in three dimensions! [discovery]
