New ultra-thin film for interference-free 5G and 6G
A research team from the Korea Institute of Materials Science (KIMS) has developed an ultra-thin film that absorbs 99% of electromagnetic waves. This technology could significantly improve the efficiency and reliability of modern communication and radar systems and ensure interference-free applications in 5G, 6G and autonomous vehicles.
With the new film made from a special composite material, KIMS is demonstrating how electromagnetic interference in communication systems can be effectively minimised. The film, which is only 0.5 mm thick, absorbs more than 99% of electromagnetic waves in frequency ranges such as 5G, 6G and WiFi. This shielding technology avoids disruptive reflections and offers unrivalled freedom from interference. An advantage that could further optimise the use of modern communication devices and radar systems.
Absorption instead of reflection
Conventional shielding materials often rely on reflection, but this is only partially effective. The new type of film, on the other hand, absorbs electromagnetic waves in a targeted manner and thus ensures a high level of interference immunity. This approach prevents waves from bouncing back and interfering with neighbouring systems. The technology is based on a unique crystal structure and a magnetic composite layer that precisely filters frequencies and ensures maximum absorption.
Flexible and dimensionally stable for a wide range of applications
The developed film shows high flexibility and dimensional stability, even after thousands of folds. These properties make it ideal for flexible and portable devices such as smartphones and electronics. It also offers reliable shielding and high durability for roll-up screens and other flexible technologies. The film remains dimensionally stable and functional even in demanding applications. Ideal for use in modern, portable devices.
Optimisation through carbon nanotubes
A thin carbon nanotube film on the back of the film further increases the shielding performance. With an absorption coefficient of 99.9%, the film ensures that electromagnetic waves do not penetrate to the outside and that interference in various mobile and autonomous applications is minimised. This innovative combination of materials creates reliable shielding, which is particularly in demand in areas with high sensitivity to electromagnetic interference.
With its high absorption and flexibility, the new KIMS film offers an ideal solution for minimising interference in modern communication technology. It enables better freedom from interference in 5G and 6G networks and could bring ground-breaking improvements in autonomous systems and portable devices – a promising development for future digital infrastructure.
