Gold Nano service Invisibility Cloak actually realized

　　Invisibility Cloak is a very common artifact in science fiction, and it was the researchers ' interests. In recent years, scientists have been working on how to manipulate objects and interactions between light, makes the object look as if it does not exist, that is to say, things disappear, invisible. iPhone 6 cases hello kitty Hello Kitty iphone 6 cases

　　Now, scientists has achieved new progress in the research of the invisibility cloak. From the United States, Berkeley Lab researchers have successfully created a thin invisible "skin" the cloak, it can-d objects, packages and hidden objects in visible light, achieving invisibility effect.

　　So far, this thin cloak was only able to make micro-objects invisible, it consists of a very thin layer of gold Nano-layers, thickness of only 80 nm. As long as it is covered in small size objects (about several biological cells, 1300 square microns in size), you can hide objects by means of reflecting optical.

　　Laboratory of Xiang Zhang, Director of materials science in Berkeley said in a press release: "this is the first time we have an arbitrary shape object hidden in visible light. Our ultra thin cloak that looks like a coat, its design and are very easy to carry, but also has a macro object hidden extensibility. "

　　It is understood that the invisibility cloak uses a specially designed materials, is different from natural materials, it is mainly through physical structures that reflect light bending, in order to achieve invisibility effect, rather than by chemical composition. When the visible light falling on the cloak of activated when Nano array inside it will be launched out of the bending of light rays from the object, which makes it look like we don't exist.

　　Just like described in science magazine, Invisibility Cloak makes objects look flat, invisible (when you look down from the top), but, you may object to any motion that illusion will be shattered. In other words, it could not reach the Harry Potter invisibility cloak that degree of cloak.

　　The researchers efforts to hide the object, but the cloak is still visible. In addition, the volume of invisible objects is a problem one has to consider. Xiang Zhang said in an interview: "If you want to hide your body, then you have anytime, anywhere with this 3 to 4 times bigger than your body. "

　　But anyway, researchers made progress in Metamaterials has successfully achieved the first true invisibility cloak technology and this technology can continue to zoom in, hiding will also, however, that people need to stand without moving.
