They manage to make objects invisible in an almost perfect
There will be an invisibility cloak like Harry Potter wearing, but does the same. This is a diamond shaped device created by scientists at Duke University in the U.S., who found an effective method will reflect light passing through a body, causing it to come across traveling through the device, regardless of the small three-inch cylinder that hides in the center, leaving invisible.
It would be the first time in history that this effect is achieved almost perfectly, as in previous attempts, always saw some distortion of light that could be seen as transparent edges marked or reflection of the objects that are in front, as we were looking at a very clean glass that despite being transparent, equal and thus reflects light, the viewer.
With the help of “meta-materials” as scientists call them, managed properties not found in natural elements in a job that is refined since 2006 until now. However, as stated above, the device is almost perfect, failing that, whether from an angle other than the front, not invisible.
Despite this, and then be an invisibility cloak in two dimensions (2D), as can be seen only from the front and move up and down, the people of Duke University and is working to make technology support three dimensions , something much more complicated but who would take the label of perfect invisibility cloak.
