According to claims from Chinese media, the material, created by the National University of Defense Technology, is designed to absorb electromagnetic waves and convert them into heat, a process that may significantly reduce the aircraft\u2019s radar visibility.<\/p>\n
The new material is said to be able to absorb electromagnetic waves with wavelengths ranging from 2.3 feet to 0.6 feet, which covers the key frequencies of most anti-stealth radars, specifically the P-band and L-band.\u00a0<\/p>\n
Chinese researchers said that laboratory tests have shown the material\u2019s ability to effectively absorb low-frequency electromagnetic waves from various angles, with a thickness no greater than two sheets of printing paper\u2014an achievement considered impossible until now.\u00a0<\/p>\n
Anti-stealth radars typically emit long-wavelength electromagnetic signals, which are difficult for current stealth aircraft coatings to absorb effectively due to their thinness.\u00a0<\/p>\n
The report said that the new material could mark a breakthrough in overcoming this limitation, potentially offering stealth aircraft enhanced protection against radar detection.<\/p>\n
The material is also described as lightweight, flexible, and easy to mass-produce, making it an attractive option for covering a range of military platforms. Chinese scientists believe this cost-effective material could evolve the production of stealth technologies for aircraft and other defense equipment.\u00a0<\/p>\n
This new material is based on metamaterials\u2014structures engineered to interact with electromagnetic waves in unconventional ways. Metamaterials are known for their ability to absorb a wide range of frequencies and manipulate light and other waves at a microscopic level. \u00a0<\/p>\n
Researchers used an unidentified metal to create a circuit within the material. When hit by low-frequency electromagnetic waves, the circuit creates currents that are converted into heat and dissipated into the surrounding air. \u00a0<\/p>\n
