China has developed a flexible, durable aircraft coating that absorbs radar waves, potentially closing a critical technological gap and redefining the future of aerial stealth. A study published on October 14 in Advanced Materials details a scalable, flexible and ultra-thin (0.1 mm) metasurface capable of withstanding temperatures up to 1,000 degrees Celsius (1,832 degrees Fahrenheit). The material features tunable impedance, making it suitable for aerospace electromagnetic wave absorption. It…
