Scientists From NUST MISIS Create the Stealth Technology That Hides Metal Masts and Antennas Completely

"We came up with a special coating based on an ideal magnetic dipole scatterer that turns an elongated metal object with an electric response into an object with a magnetic response," said one of the researchers, associate professor at the NUST MISIS Superconducting Metamaterials Laboratory, Alexey Basharin. "This has become possibledue to the anapole state of the coating material, which lowers the electric type scattering to the level of the magnetic one and even lower. As a result, the object becomes invisible."

The first of the possible applications of the new coating will be STEALTH technology for military and civilian purposes - to hide various elongated objects, such as aircraft landing gear, antennas and various sensors, ship masts and airport towers. The developers emphasize, that if the task of hiding these objects from enemy radars is trivial, the task of electromagnetic compatibility of antennas on satellites is vital: antennas must not affect each other. And this will be possible only if they are invisible.

The method will help hide the structures of airports, operator towers so that they do not interfere with radar and communications with pilots. Besides, the development will find application in the so-called "Magnetic light" tasks, where it is necessary to enhance various magnetic phenomena: in nano-antennas, nano-lasers, etc.

The research of the team is a theoretical work and demonstrates new methods and open effects. The next stage of the project and the immediate goal, according to the researchers, is to learn how to reduce the magnetic response of elongated metal structures.
