Radar absorbing materials (RAMs) have gained a fundamental role in civil, aerospace and military applications that require a good control of the electromagnetic (EM) environment such as design of ‘stealth’ aircraft against air based radar surveillance. Such materials are characterized not only by high shielding properties against EM fields but a low reflection coefficient over a defined frequency range of EM spectrum. The objective of ‘stealth’ designs is to reduce the radar cross-section (RSC) of the potential targets in order to make aircrafts and vehicles less detectable to hostile radar surveillance systems. In RAMs, the absorption is primarily due to the material’s dielectric and magnetic characteristics. Furthermore, the periodic patterned structures would be responsible for creating multiple absorptions by electromagnetic wave scattering based on structural influence. We propose radar absorbing 3D meta‐materials composed of ferrite multi‐granular nanoclusters (MGNC) carbon nanotubes/graphene nanocomposites. The optimized 3D meta structure is designed by electromagnetic simulation study.
