American scientists say they are close to developing materials that can make humans invisible. Researchers at the University of California, Berkeley have modeled a blanket that does not reflect light, but forces it to bend around objects, making them invisible. True, this technology can only be used for small objects and, theoretically, for humans.
The researchers helped to achieve success in a unique experiment with nanotechnology. The fabric of the bedspread is made of the so-called metamaterial with a special structure. It has properties that are not found in nature. As an example of how this matter works, scientists cite a stream that bends around a stone.
We see objects around us by the light reflected from them. If the reflection of light rays is somehow prevented, the object will become invisible. However, according to the researchers, the ability to redirect light only works at a limited wavelength, so new materials cannot make truly large objects, such as buildings, invisible, according to the BBC.
Scientists joke that "cloaks of invisibility" made of such material will be very useful for a wide variety of consumer groups - from the newly minted Harry Potters and debtors hiding from creditors to unfaithful spouses and military intelligence officers.
The unique technology can already find wide application in various fields. For example, this material can be used where glare suppression is required, as well as to increase the resolution of microscopes.
But it is unlikely that we will be able to see the "invisible people" not only in the near, but also in any distant future, say the researchers. After all, the invisibility cloak not only isolates its owner from others, but also deprives him of the opportunity to see anything happening outside. After all, light from external objects flows around the cloak over the surface, without getting inside.
