Radar Absorbing Materials (RAM) absorb the incident Electromagnetic (EM) energy and convert that energy into heat or any other forms. The energy output will be same as that of the energy input. Radar absorbing materials are used to reduce the level of electromagnetic energy scattered from its surface. Earlier, this technology was primarily used for military applications including land, air, and sea vehicles. Innovation and advancement in the technology has widened its scope and is now being used for civil as well as commercial applications. It has been used at airports and in wind turbines to reduce radar scattering to prevent the interference. The main advantage of radar absorbing materials is that it can be designed and operated at any frequency within the electromagnetic spectrum.
Radar absorbing materials are made from resistive and magnetic materials. The materials for reduction of radar cross section is primarily dependent on electric as well as magnetic materials. Radar absorbing materials provide a reduced signature for detection. Radar absorbing materials and structures include iron ball paint, foam absorbers, and Jaumann absorbers. The design of absorber structure is based on the optics principles. Radar Absorbing Materials can be broadly classified into impedance matching and resonant absorbers. Radar absorbing materials market is expanding and is expected to witness a significant CAGR growth over the forecast time period of 2016-2026.
