Recently, a Chinese scientists published in the English paper caused the western media speculation.On November 10, the physics of the federation of the journal of applied physics published an article in the 118 issue of the author from the huazhong university of science and technology English papers in China.The paper expounds the "active frequency selective absorbing surface" technology is used to absorb ultra-high-frequency (UHF) band radar technology.This is considered a kind of can be used in the manufacture of stealth fighters of the smart skin technology, it can adjust itself according to enemy radar detection frequency of radar wave absorption rate, thus greatly reduce the radar echo area, may make only absorbs existing fixed band wave stealth coating technology is completely out of date.After observer network query related papers in Chinese, find and associated parts of the paper before and after test as early as in 2011 has been completed, the technology may have been close to practical application, so relevant preparatory academic achievements have been published.
The "art" of science and technology website (Arstechnica) according to the report, Chinese scientists have developed a new material, known as "active frequency selective surface" - that is a very thin layer of material, the surface is a layer of material for printed circuit board, below the semiconductor and copper structure, after electrify the can to a certain frequency range to absorb microwaves, and absorb specific band is adjustable.This material can reduce any it covers the radar cross-section of reflection of the object, such as stealth fighter.Once put into use, it will be able to absorb the radar wave of different frequency.Importantly, the working principle of equipment have been publicly, in the recently published in the journal of applied science.
