Invisibility cloak is being improved!Invisibility cloak is being improved!
After a few years we could be invisible like science fiction movies. Researchers develop a cloak that will be invisible when worn, light and chestnut will not be noticed.
With the Harry Potter film, the invisibility that most people imagine is technically possible. In Austria, researchers at TU Wien developed a process that made the target invisible by drawing a simultaneous wave pattern of the correct light waves over an opaque material.
The cloak of invisibility will not be noticed by light and stalk
Technically one day it is possible to produce a cloak that will make us invisible in both light and sound waves. The objects are visible to us, thanks to the light-wave fluctuations that bounce off some things in our retinas. Many of the previous attempts at cloaking have tried to counter this principle by bending the light waves around objects. But he could only work on small scales and often created other visual effects such as a brilliance effect.
TU Wien researchers use a special material and a special wave technology, indicating that the invisibility feature gives much better results. The researchers, guiding the original wave of light through the object, obtained an image as if the object had never existed there. Optically active material, when energized, indicates that it behaves differently than materials used in previous studies.
The TU Wien team has so far tested only the cloak in computer simulations. As the next step, practical testing is planned. The cloak is thought to work theoretically for acoustic concealment. For this reason, the researchers indicate that the experiments continue for sound waves.
