Breif introduction of diamond nanopowder as RAM:

Radar-absorbent material (RAM), is a class of materials used in stealth technology to disguise a vehicle or structure from radar detection. A material's absorbency at a given frequency of radar wave depends upon its composition.

With the development of science and technology, various detection methods are becoming more and more advanced. For example, the portal uses radar launch, electromagnetic and magnetic waves to detect aircraft, and infrared detectors can also be used to find infrared objects.

A small amount of nano-diamonds are suspended in the paint and sprayed on aircraft, tanks, missiles, and military ships, which can play an invisible protective role. It is much simpler and more efficient, and reduces the production cost, which is conducive to the rapid mass production of new semiconductor electronic materials.

Why are superparticles, especially nanoparticles, invisible to infrared and electromagnetic waves?

There are two main reasons: on the one hand, since the size of nanoparticles is much smaller than the wavelength of infrared and radar waves, the transmittance of nano particle materials to this wavelength is much stronger than that of conventional materials, which greatly reduces the reflectivity of the wave, which makes infrared detectors and radars receive very weak reflected signals, so as to achieve stealth. On the other hand, the specific surface area of nano powder materials is 3 or 4 orders of magnitude larger than that of conventional coarse powder, and the absorption rate of infrared light and electromagnetic waves is larger than that of conventional materials, which greatly reduces the reflected signal intensity obtained by infrared detectors and radars, so it is difficult to find the detection target, which plays a stealth role.
