par Beochien Sam 12 Mar 2016 - 0:08On n'arrête pas le progrès (Ni les coûts) sur les "Peaux" non réflectives ... aux ondes Radar !
Va pour une étude de l'université du IOWA, menée par des Chinois (
)
Ca concerne des polymères, meta-materials, et autres objets métal liquides, bon, des composites, pas comme les autres !
Ca a l'air complexe, et peu expliqué à ce stade, mais bon, la bataille continue entre stealth et détection !

Iowa State University engineers have developed a new flexible, stretchable and tunable "meta-skin" that uses rows of small, liquid-metal devices to cloak an object from the sharp eyes of radar.
The meta-skin takes its name from metamaterials, which are composites that have properties not found in nature and that can manipulate electromagnetic waves. By stretching and flexing the polymer meta-skin, it can be tuned to reduce the reflection of a wide range of radar frequencies.
The journal Scientific Reports recently reported the discovery online. Lead authors from Iowa State's department of electrical and computer engineering are Liang Dong, associate professor; and Jiming Song, professor. Co-authors are Iowa State graduate students Siming Yang, Peng Liu and Qiugu Wang; and former Iowa State undergraduate Mingda Yang. The National Science Foundation and the China Scholarship Council have partially supported the project.
"It is believed that the present meta-skin technology will find many applications in electromagnetic frequency tuning, shielding and scattering suppression," the engineers wrote in their paper.
