Radar absorption for military purposes with the use of ferrite material mixtures can be achieved by compression moulding of the pigment mixtures into small plates or platelets, or by introducing the pigment mixtures into paint, resin, plastics or plastic sheets. The absorption effect in ships, aircraft, rockets (satellites), motorised vehicles (tanks) and other solid targets of all types is achieved by laying on, coating, spraying, painting or covering with plastic sheeting. The properties result from appropriately defined, selected ferrite material mixtures and additives such as, for example, graphite in a suitable composition according to frequency ranges. The types of the ferrite materials and the additives result from the frequency function requirement and intensity according to the various applications. The composition process is carried out in pigment form. The physical limit is above 100 GHz. A coated target area provides less spectral energy, compared to the saturation behaviour of ferrite cores in the resonant circuit, the saturation factor of the absorption layer over the echo-generating surface resulting from field attenuation theory. The absorption intensity increases with the material thickness and with the composition of the mixture and, in the case of optimum sizing, has the advantageous effect of highly efficient overall absorption. The frequency limit is defined by the magnetisation intensity. This type of absorption ... Original abstract incomplete.
