IIT Mandi develops new technology to make military equipment invisible to radar
Being invisible to radar is a crucial defence strategy and the ability to evade radar detection can reduce the chances of being targeted by enemy weapons.
Researchers at the Indian Institute of Technology (IIT) Mandi have created an artificial material that can make stealth vehicles as well as covert establishments less visible to the radar.
This material can absorb a wide range of radar frequencies (signals), irrespective of the direction from which the radar signal hits the target. It can also be used to cover windows of stealth vehicles and covert establishments that must be invisible to radar. The results of this work is published in the journal, IEEE Letters on Electromagnetic Compatibility Practice and Applications.
What are radars used for?
Radars are used in defence and civil sectors for surveillance, and navigation, to detect and track: aircraft, ships, ground vehicles, and movements within covert establishments. Being invisible to radar is a crucial defence strategy and the ability to evade radar detection can reduce the chances of being targeted by enemy weapons.

After JEE session 2 is completed, only those candidates who are aiming for IITs need to start preparing for JEE Advanced after clearing JEE Main. Those who are above the 98th percentile should start preparing for JEE Advanced as soon as possible. Those below this, between the 95th and 98th percentile, should focus on attempting more mock tests and previous year question papers so that they have a better chance of clearing JEE Advanced

Any technique that makes things invisible to radar 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 the protection of information and privacy.
Radar Cross Section (RCS) reduction is a way to make something less visible to radar. It is achieved by using materials that can absorb radar signals, or by shaping the object in a way that makes it difficult for radar to detect.
Explaining the research, Dr G Shrikanth Reddy, IIT Mandi, said, “We have developed a technology based on Frequency Selective Surface (FSS) that absorbs a wide range of frequencies used in radar, which makes the surface invisible to radar.”

Candidates shall bring originals and copies of all the necessary academic certificates, JEE scorecards, address proof, ID Proof , passport-size photographs, etc.
Candidates with a proven academic record based on a cut-off of the GATE, CSIR or UGC scorecard or equivalent are eligible to apply for PhD at IIT Jodhpur. The institute shortlist students based on their score in the entrance examination. Shortlisted students need to appear for the personal interview round. Candidates further must hold the relevant documents as a proof of eligibility.
The proposed design uses an optically transparent ITO-coated PET sheet where the FSS patterns are created on this PET sheet. The FSS pattern on the PET sheet were created with the laser engraving technology, and due to symmetrical and lossy nature of FSS patterns, the proposed absorber is polarization insensitive and absorbs a wide range of EM wave frequencies within C, X and Ku Band.
Tests showed that this FSS technology can absorb more than 90 per cent of the radar waves in a wide range of frequencies. The team performed experimental studies on their design and the results matched well with the theoretical analysis, verifying its effectiveness.
