IIT-Mandi develops tech to make Army equipment invisible to radar.

February 8, 2023

Res earchers at the Indian Institute of Technology (IIT) have created an artificial structure/material that can make stealth vehicles and well as covert establishments less visible to a radar.
This material can absorb a wide range of radar frequencies, irrespective of the direction from where signals hit the target. It can also be used to cover windows or glass panels of stealth vehicles and covert establishments that must be invisible to radars.
- Being invisible to radars is a crucial defence strategy and the ability to evade radar detection can reduce chances of being targeted by enemy weapons.
Any technology that makes things invisible to radars can also be used in the commercial sector to reduce radiation leakages from buildings and make them more secure. For example, invisibility to radar can also be used in private or covert establishments for privacy.
The material has been developed using the technology based on frequency selective surface (FSS) that absorbs a wide range of frequencies used in radars, which makes surface invisible to radars.
