Russian scientists have created a unique metamaterial with stealth properties

70
In a reputable scientific journal Physical Review An article appeared, the authors of which are Russian scientists from NITU "MISIS" of the city of Moscow. The article talks about the development of a unique metamaterial, among the many surprising properties of which is the ability to remain "invisible" for the whole spectrum of electromagnetic radiation. Such metamaterial, as reported, can be used to create equipment with unique stealth technologies (new stealth options).


Russian scientists have created a unique metamaterial with stealth properties


It is known that not only physicists from Moscow, but also Greek scientists from the University of Crete were involved in the creation of technology. It should be noted that the work was carried out in the framework of the Russian-Greek cooperation in the field of quantum technologies. The corresponding contract was concluded in 2016 year. Cooperation is financed by both countries (the Russian Federation and Greece) and provides for the creation including the mentioned metamaterials.

For reference: metamaterials are artificially created materials. They have a heterogeneous internal structure, which allows the electromagnetic wave to be “lost” inside such a material. This may allow the use of metamaterials as a kind of “invisible cap” for modern combat vehicles. It is reported that metamaterials may be suitable for creating advanced computing and communication systems with photon principles, rather than electrical ones.

From the statement of the representative of NUST "MISIS", Associate Professor Alexei Basharin:
The experimental part of our research is a unique metamaterial created, which is a small flat lattice of so-called metamolecules cut by laser cutting from a single piece of ordinary steel. When a nonlinear semiconductor is added, the metamaterial will become a tunable screen for STELS technologies — a set of ways to reduce the radar visibility of combat vehicles in radio, infrared and other spectral regions.

              They pour a semiconductor on top. I am more worried about the word "small". What does it mean? Month need to cut a square millimeter? Or after exceeding a couple of microns of the area, the properties are lost?

                For a wave of 3 cm, the 1x1 cm grid will already be a solid screen, indistinguishable from a piece of steel. (This is how solid antenna mirrors make it easier - a metal mesh in carbon fiber reinforced plastic) It makes no sense to make cells smaller. In the mm range, "transparency windows" of 8mm and 3mm are used. "Reconfigurable" - most likely meant active switching keys that change the size of cells. But this is so, an assumption. The journal is really authoritative, but it is in the sections of physics with letters. There is no link or number in the article. And there is no hope for journalists.

            A metamaterial is just a coverage of an object, not the object itself. Such a coating has a negative refractive index of electromagnetic waves that do not reflect, but flow around the object so that the background on which it is located is visible behind the object. Those. the object becomes in the full sense invisible (in a certain range of the electromagnetic spectrum, of course).

            This effect is fundamentally different from the absorption of radiation using a ferromagnetic coating in the framework of stealth technology, when the object is visible in the light as a dark region.

            A metamaterial is a regular structure consisting of many simple resonators, oscillatory circuits, etc., made of metals and semiconductors on a ceramic or plastic substrate. The size of the elements varies from millimeters or less, depending on the wavelength of electromagnetic radiation.

            Elements or the surface as a whole are manufactured using 3D printing, laser cutting, photo printing and subsequent etching (as integrated circuits).

            The most promising field of application of metamaterials is coatings for ICBM warheads, which make them invisible in the extra-atmospheric section of the flight path.

            The laser diffraction grating can be applied in principle to any surface, it just happens by evaporation of the material from the surface. if the surface is first covered with a semiconductor layer (moreover, it is a semiconductor and the thinner its layer, the more pronounced its properties are), then with a laser the conductor layer is vaporized, then we get a diffraction grating of alternating strips of steel and a semiconductor, here’s the metamaterial (

              One of the simplest and most common everyday examples of reflective diffraction gratings is a CD. A track in the form of a spiral is cut on the surface of the CD with a step of 1,6 μm between the turns.

              The metamaterial cube is a three-dimensional matrix formed by copper conductors and split rings. Microwaves with frequencies around 10 GHz behave unusually in such a cube, because for them the cube has a negative refractive index. Lattice pitch - 2,68 mm, or about 0,1 inches

            Well, maybe the task of the semiconductor is to just absorb waves of a given frequency, maybe the frequency of the waves can be adjusted by applying some kind of voltage to the material - here, I'm sorry, not special, but I have not looked at the article in the journal yet, work.

              In the same way, the main property of the diffraction grating is the separation of the radiation incident on it along the wavelength. No more and no less.

              1. Theoretically, selective absorption of EM radiation by a semiconductor is possible. But what does the diffraction grating have to do with it?
              2. The trouble is that this takeover will be just that selective.
              3. This absorption for known systems occurs in the light range, and not in the radio range.
              4. In addition, this absorption in existing semiconductors is ineffective - and for radar invisibility, complete absorption is needed.

      Add a pheromagnet into the paint (powder phyrite — the electromagnetic component is well extinguished). We paint (by the type of enameling - we sinter) the tank (it will not bear the weight of the plane). So the absorption of 99% of the exposure of the millimeter and centimeter ranges is almost stealth. There will be no problems with the L-band. There the antennas are large and they will see it no further than a few km - there is a push for it! A tank is a piece of metal - you will have to demagnetize it - like ships.

      For example, the antenna outputs of aviation microwave emitters / receivers as old as fifty are glued with rubber (inset of a waveguide or bottle antenna into the aircraft skin, usually for a copper transmitter - a heat sink from rubber, receivers - duralumin) with a ferromagnet around the perimeter (5-10 cm) to isolate from the case itself not by the electric, but by the electromagnetic component. Its thickness is ~ 4-5mm. In the insert of the antenna there is a milled recess on the same 4-5mm for rubber. It will not work to glue the aircraft - 1dm square 120-150gr. + Very good heat-conducting adhesive - work at -60 + 85 and not be torn off by the air stream. It made magnificent fly swatter!

          do not confuse invisibility in the radio bands and in the visible part of the spectrum.
          if the surface does not reflect but absorbs the impulse from the radar, then for the radar it is invisible, but this does not mean that it cannot be seen with the eyes. By the way, if you teach the radar to analyze not your reflected signal, but the entire spectrum of radio waves that will come to the receiver, as the human eye and brain do, then coating surfaces with radar absorbing materials will be useless - the object will be visible as a black body
          Judging by the article in VO, the material will be able to absorb radio waves with a given and variable frequency - it's just fantastic - you do not need to cut the foil along the wavelength to expose the interference, but simply change the voltage potential to the aircraft body and the mark disappears on the radar.

              Alas, I am forced to do the work that was not completed in high school by your physics teacher. laughing

              The EMP wavelength can be from hard gamma radiation, with a wavelength of less than 0,2 nm and a photon energy above 0,1 MEV, to a long-wave radio range with a wavelength, for the range of 30 kHz, at 10 km. Moreover, the connection of the parameters is simple: L * F = C, E = h * F.
              ALL types of EMP in a vacuum propagate at the speed of light C.
              F - frequency, L - wavelength, h - Planck's constant.

              Visible light occupies the range between IR and UV, with a wavelength of 380 to 750nm. The yellow line of sodium is 590mm, in the standard RGB, the main colors are 650, 510, 475nm.
              The difference between visible light and other EMPs is that our eyes are able to perceive visible light directly, we can feel infrared radiation with our skin like heat, with sufficient power.

                  The difference between radio waves and visible light, in terms of location application, is primarily that radio waves are able to pass through clouds / fog / dust without absorption and scattering.
                  Therefore, hundreds of kilometers are possible for radar, but not for visual detection.
