The US is producing thousands of invisibility cloaks

People who are interested in the invisibility cloak may be shocked to learn that a team of American researchers has produced 25,000 such shirts.

According to the Science Daily, the special feature of the invisibility cloaks is the microscopic size: only 30 micrometers in diameter (one micron = 0.001 millimeters). They are arranged in the form of a 25 mm gold plate next to each other.

These are the first such invisible cloaks in the world and are the brainchild of researchers from both Towson University and the University of Maryland.

Although they have not been able to ' cloak ' objects that cover themselves like Harry Potter's invisibility cloak, the invisibility cloak developed by the group of American scientists has the potential to slow down and even Light blocking, help 'captive' rainbow.

Mechanism 'captivity' rainbow is described as follows: When rated isoforms on the gold plate, each of the of the 25,000 cloak possess a lens elves have the ability to bend light around it , conceals an area in the center of it. As light goes through the gaps between each shirt, different parts of the light (color) are blocked at narrower points, creating a rainbow.

The 'captive rainbow' technology can be used in micro-biological sensors to help identify biological materials based on the amount of light they absorb and then emit. Compared to light traveling at normal speed, light is accelerated to interact more intensely with molecules, resulting in more detailed analyzes.

Dr. Vera Smolyaninova, lead researcher, said: The benefit of bi-chip microarchitecture is that you have a large number of small sensor devices, supporting multiple experiments. For example, you can test multiple gene states in a person's DNA in the same experiment.

In the layout of our invisibility cloak, light was blocked at the boundary of each shirt, allowing us to observe the captured rainbow at the edge of each shirt. That means we can make "on-a-chip spectra" and test fluorescence at thousands of points at once.
