“Ruselectronics” has developed a stealth material to ensure the “invisibility” of aircraft

Ruselectronics Holding has created prototypes of a fundamentally new material capable of absorbing radio waves in a wide frequency range. Due to the basis of glass fibers with a metal core, a thin-layer material can be used to manufacture aircraft parts. This design solution is proposed for stealth materials for the first time.
