A special coating has been developed that absorbs radio waves, making unmanned aerial vehicles nearly "invisible" to radars. This has been reported by a number of foreign publications.
It is noted that the material does not reflect the signal like conventional coatings. Instead, it absorbs radio waves and converts them into thermal energy. This significantly complicates the detection of a drone or other object through radar systems.
The company that developed the technology offers three types of coating for different frequency ranges. In particular, the C105 version provides protection against radars in the X and Ku bands. The C112 model is designed for systems operating in the S and C bands. The universal C113B type covers both bands.
Applying the coating to a surface does not require special industrial infrastructure. The manufacturer offers the product in 1, 5, and 10 kilogram containers, which further facilitates its practical application.
It is reported that a coating with a thickness of 0.40–0.60 millimeters can reduce the reflected signal level by 3–3.5 decibels. This means the signal power is approximately halved.
The weight of the coating does not exceed 1.1 kilograms per square meter. The material retains its properties for 100 hours at temperatures up to 250 degrees. It is also resistant to prolonged vibration and has successfully passed 2,000 hours of testing in saline fog conditions.
According to experts, such technologies can be widely used in marine and coastal facilities, as well as in the military and industrial sectors.
