Employees of the Moscow Institute of Steel and Alloys are currently developing and testing the latest method of data transfer using special metamaterials. The development is completely unique, since even the metamaterials themselves are made on the basis of MISiS in a laboratory working with superconductors.
To begin with, it is worth explaining what the metamaterials are. Metamaterials are artificially created substances and compounds that, because of their structure, can control electromagnetic radiation, changing the direction or properties of certain waves. In addition, metamaterials make it possible to hide objects from observation in certain ranges of electromagnetic radiation. Metamaterials can be used in a variety of ways, but one of the most promising is the production of fundamentally different computers. Metamaterials can be used to create machines that will operate on photonic rather than electrical connections.
Metamaterials and superconductors created by scientists from MISiS can also be used as extremely sensitive sensors capable of detecting even extremely small amounts of specified substances. This, for example, can be useful for determining explosives, when searching for drugs and other counterfeit products, and also for searching for harmful impurities (GMOs, antibiotics) in food.
In addition, superconducting metamaterials can be used to covertly transmit information, which is carried out by modulating the vector potential. This signal is very stable and it is extremely difficult to detect and intercept.
