There's some pretty advanced math behind it all—scientists need to use it to find how to set up the two lenses so that the light is refracted in such a way that they can hide the object directly behind them. This solution works not only when looking directly at the lenses - an angle of 15 degrees or another is enough. It can be used in cars to eliminate blind spots in mirrors or in operating rooms, allowing surgeons to see through their hands.

This is another in a long cycle of revelations about invisible technologies that have come to us in recent years. In 2012, we already heard about the "Cap of Invisibility" from the American Duke University. About what it was about invisibility of a small cylinder in a small part of the microwave spectrum. A year earlier, Duke officials reported on sonar stealth technology that may seem promising in some circles.

Unfortunately, it was only about invisibility from a certain point of view and to a limited extent, which made the technology of little use. In 2013, the tireless engineers at Duke proposed a 3D printed device that camouflaged an object placed inside with micro-holes in the structure. However, again, this happened in a limited range of waves and only from a certain point of view. In photos published online, the cape of the Canadian company with the intriguing name Quantum Stealth looked promising.

Unfortunately, working prototypes have never been demonstrated, nor has it been explained how it works. The company cites security issues as the reason and cryptically reports that it is preparing secret versions of the product for the military. We invite you to read the issue in stock.
