The people have been a long time fantasies about an invisibility cloak or the same hat. All this was carefully described in fairy tales. But recently scientists could come close to developing the development of such things in reality. A material was created with such a pattern that makes the object invisible.
How did manage to create all this? Scientists just took a tissue, which was then irradiated with a wave pattern. Initially, the material was not transparent. The pattern repeated all the irregularities of the fabric. Usually, these irregularities just scatter light. Scientists managed to achieve that the rays began to pass through the tissue, as if it were not there. They do not seem to meet obstacles in their way. All this was done at the University of Vienna.
The selection of a pattern for a specific tissue is carried out using a computer program. At the moment, such a selection is possible for all materials known to people.
