scientist at the University of Rochester (USA), John Howell, and his 14 year old son, Benjamin , have created an invisibility cloak that is capable to hide large objects in all kinds of optical spectrum. The author pointed out, moreover, that it is a device of “low cost” and “simple” that works “surprisingly effective”.

Invisibility is an issue that has been debated for time both in popular culture and in the scientific community. Invisibility means hide a view object at specific frequencies, and different types of camouflage. So far, studies only managed to ‘hide’ objects to some frequencies and small objects.

The system devised by Howell family, whose work has been published in Arxiv , consists of three devices . Plexiglas first and buckets as L. The second uses four lenses for optical camouflage, while the latter uses a set of m irrors, a system used by magicians in their tricks.

The weak point of this technology is that it only works in one direction With these mechanisms is achieved ” bend “light in a given space and hide an object . And, as explained by the researcher, all these materials has been made in cheap shops and the total budget of the experiment has been $ 150. In addition, it could play a large scale.

But this achievement also has “some limitations” , as acknowledged Howel, who noted that “the weak point of this technology is that only works in one direction, or assuming that the observer will not move from its place. ” Still, it has more advantages than other systems presented above by scientists.
