A team of researchers from the Indian Institute of Technology (IIT) has invented an innovative artificial material that can make stealth vehicles and covert establishments less visible to radar detection. This cutting-edge material has the capability to absorb various radar frequencies, regardless of the direction from which the signals hit the object. It can also be applied to cover windows or glass panels of stealth vehicles and covert establishments to make them invisible to radars.
According to Dr. G Shrikanth Reddy, a faculty member at IIT Mandi, radars are commonly used in both defence and civil sectors for surveillance and navigation. They are used to detect and track aircraft, ships, ground vehicles, and movements within covert establishments. Being undetectable by radars is a crucial defence strategy, and the ability to evade radar detection can significantly reduce the chances of being targeted by enemy weapons.
Dr. Reddy further explains that any technology that makes objects invisible to radars can also have commercial applications, such as reducing radiation leakages from buildings and increasing their security. The technology can be used in private or covert establishments to ensure privacy.
The innovative technology is based on a frequency selective surface (FSS) that absorbs a wide range of frequencies used in radars, making the surface invisible to radars. Tests have shown that the FSS technology can absorb over 90% of radar waves in a wide range of frequencies. The team conducted experimental studies on their design, and the results were consistent with the theoretical analysis, demonstrating the effectiveness of the technology.
The application of this technology can be utilized in defence operations to reduce or eliminate the radar signature of military equipment, including aircraft, ships, and other vehicles.
