When electromagnetic radiation enters iron ball paint it is absorbed by the ferrite or carbonyl iron molecules which causes them to oscillate. The spheres are coated with ferrite or carbonyl iron. One of the most common RAMs is called iron ball paint, which contains tiny metal-coated spheres suspended in an epoxy-based paint. Most RAMs consist of ferromagnetic particles embedded in a polymer matrix having a high dielectric constant. ![]() Information about the composition of RAMs is guarded by the military. Examples of stealth aircraft that use radar-absorbing materials: (a) F-22 Raptor and (b) F-35 Lightning II.
