Researchers at Graphic Era Deemed University have secured a patent from the Government of India for a breakthrough in stealth technology. The achievement comes from the university’s Department of Electronics and Communication Engineering.
Scientists Wariz Panwar and Vikas Rathi developed a thin Electromagnetic Interference (EMI) shielding film. The film absorbs radar signals in the 12–18 GHz (Ku-band) range. Once applied to aircraft, it prevents radar waves from reflecting back, making them nearly invisible to radar detection.
The invention emerged from the university’s Sensors and Actuators Laboratory. After extensive experiments, the team confirmed that the film absorbs radar waves instead of bouncing them back.
The coating can be applied like ordinary paint, which makes it practical for use. Potential applications include defence aircraft, guided missiles, electronic warfare, satellite communications (DTH, VSAT, mobile links), avionics systems such as in-flight internet, and next-generation electronics like 5G networks and microwave imaging.
Dr (Prof) Kamal Ghanshala, Chairman of Graphic Era Group of Institutions, described the discovery as a “remarkable gift” to the nation. He praised the researchers for contributing to India’s technological strength and highlighted the university’s legacy of patents across healthcare, renewable energy, and artificial intelligence.
The newly granted patent, valid for 20 years, strengthens India’s capabilities in advanced stealth technology and showcases Uttarakhand as a hub for high-impact innovation.
