Scientists at UC Berkeley create super-thin invisibility cloak



Aside from Harry Potter and his pals, no one has really managed to go invisible yet. However, it seems that this trick could be a reality in the near future – at least that’s what indicates a new research developed at University of California, Berkeley.

Dr. Xiang Zhang and his team have succeeded in creating an invisibility cloak in their lab. It is only 80 nanometers thin and, for now, has only been used in microscopic objects, but the future looks promising. In the tests, they were able to make an object of 36 square micrometers – which is equivalent to a small amount of live cells – disappear.


The invisibility cloak consists of small gold “nanoantennas” that reflect the light waves away from the object. According to the study, “the skin cloak comprises a metasurface with distributed phase shifts rerouting light and rendering the object invisible.” The operating principle of this cloak should also work on larger objects, but needs to be further developed of the creation of a larger prototype, since any movement would break the invisibility “spell” .

It is worth noting that this is not the first time that a research shows the possibility of creating invisibility covers, but this one is especially promising because of its ability to adapt to different environments and bodies. Nevertheless, This technology still needs a lot of development, since it is not yet able to reflect all the wavelengths in the visible spectrum.
