Chinese scientists developed a new fighter jet cloaking material, only a few inches in width, considered a breakthrough for the stealth fighter jet industry.
Cloaking materials have been researched in a great amount of detail. They provide any nation owning such technology significant advantages when entering an enemy’s airspace. The U.S. has been unquestionably the worldwide leader in this defense area.
For instance, the F-35, F-22 fighters as well as the B-2 Spirit bomber are endowed with stealth technology allowing them to avoid radar reconnaissance. And while the technology is successful in either reflecting the radar radio waves or absorbing them and turning them into heat, there are still radars than can pick up on traces. One such example is the ultra-high-frequency radar (UHF).
In a breakthrough announcement China announced that Chinese scientists developed a new fighter jet cloaking material. China is certainly catching up on stealth technology development and the new material is living proof.
The new cloaking material is covered by a 0.4 mm layer of copper transistors, amounting to what scientists refer to as an active frequency selective surface material (AFSS). The new cloaking material is aptly absorbing microwaves, avoiding their reflection which may lead to the detection of the fighters, spying planes or drones.
Chinese scientists with the Huazhong University of Science and Technology worked on the developing of new stealth technology. The new material is both thin and light and highly permissive in applications. Moreover, it is claimed to withstand even UHF radars functioning with the same capacity of absorbing microwaves.
The research findings are curiously published in the Journal of Applied Physics. The researcher team stated:
“In this paper we present an ultra-thin broadband AFSS absorber with a stretching transformation pattern for use in UHF applications”.
The publication of the study is a curious case. While the technology could be used to improve the capability of the Chinese military in the face of modern technology like UHF radars, the researchers chose to make it publicly available.
