Thanks to science, now you can be invisible
In recent years, this seemingly magical concept as “invisibility” has become the object of increasing interest of scientists. All this is due to the achievements in the field of materials science. UEx students in their works studied the electromagnetic properties of certain materials, with the help of which you can be invisible. The researchers used artificial substances known as metamaterials or substances with high dielectric and magnetic constants in their development.
The idea of invisibility using fillers came thanks to the project of Albert Sern and Luis Molin, students of telecommunications UEx.
“When someone talks about invisibility, we all present Harry Potter’s Invisibility Cloak. And it is this model that all other scientists have used to achieve their goals in this field. In fact, the idea of fillers, previously proposed in the novel by H.G. Wells “The Invisible Man” is more real. There Griffin becomes invisible when he is injected with a lightening agent,” researcher Alberto Cerna, who is currently working on a doctoral thesis at a telecommunications group pe UEx explains.
The scientist further comments “Most of the methods by which invisibility cloaks are developed use rare properties of certain materials. Their uniqueness lies in the fact that they allow the light to bypass an object that should become invisible.”
But still, this model cannot become a reality with the use of the usual science fillers, because the object is exposed to the influence of light and in any case forced to interact with it.
“We used a different technology, plasmon masking, which makes both the object and the filler invisible,” Serna says from Italy, where he is currently in a research internship.
Thus, this method allows you to achieve invisibility from within an object without additional use of any external device. In addition, invisibility with the introduction of plasmonic substances allows the object to interact with the surrounding things without compromising external masking.
The technique is still suitable for an object with small parameters. While the results are still doubtful, researchers believe that the prospects for improvement are promising.
Is it possible become invisible now?
Luis Landesa, supervisor of this work, argues that the idea of fillers opens up a new spectrum of science, “because the fact that the object can be “visible” from the outside without interference from the outside layers is new and a promising path of development.”
Researchers suggest that this achievement can be used in a variety of fields of science and even in bioengineering. A typical example of the utility of invisibility is microscopic probes that do not disturb the structure of the measured device. In addition, there will be no impact on the data using fillers, which was usually a problem created by invisibility cloaks.
