Invisibility Technologies

Invisibility is often used in movies to express a magical feeling in the minds of the viewers. The word ‘invisible’ itself is magical and needs a lot of connotation. When something is invisible, it creates a magical effect and a questioning mind and this makes the viewers probe into the field of invisibility technology. Really is there something called invisibility cloaking? Fictional movies have used invisibility cloaking to make something disappear for some time and when the cloak is removed, the thing or the person appears again. In 2008, a physicist named Michio Kaku prophesied that a feasible invisibility device like the ones used in Star Trek can emerge from research laboratories. He also quoted David Smith of the Duke University who had used meta-material to bend light around an object and also he quoted that German scientists have found that a meta-material can make the red light go around…

You Can Be Totally Invisible With This Invisibility Cloak!

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…

The New Breakthrough of The Invisibility Cloaks!

If you’re one of the Harry Potter fans, you’ll know that the Harry has an invisible cloak, which it will make the body disappear, once the person put on it. Believe it or not, a group of researcher from the University of California at Berkeley and the Lawrence Berkeley National Laboratory have been created a material that can bend visible light in three dimensions and the sizes is in the Nanoscale, which it can be measured in billionths of meter! Although this is really a shocking and advanced breakthrough in the metamaterials field, however it still has two severe limitations. Firstly, it will only work on the microwave range of the light spectrum and secondly, it will only work on thin, two-dimensional systems!
