Stealth knowledge is used to make the object less observable and is defined in terms of absorption of electromagnetic waves that is an important research area used in defence research. Radar cross-section is the proportion of the objective's capacity to reflect radar signals toward the radar beneficiary. Some techniques such as shaping, radar absorbing material (RAM), passive cancellation and active cancellation have been used for RCS reduction purposes. For a long time, radar absorbing material (RAM) has been actively pursued. For RAM weight, design, thickness, mechanical strength and absorptivity are key factors and therefore in the development of RAM, there is a trade-off between weight and thickness of absorber material. Along with this, an alternative to RAM is RAS and metamaterial are one of the possible options. The metamaterial is lightweight and easy to use. The Stealth property of metamaterial is based on material property i.e., permittivity and permeability of material varying from small positive to large negative values at a particular frequency. In this paper, we hada novel study of metamaterial and its various aspects.
