Metamaterial absorber (MA) is of particular interest due to its numerous potential applications in sensing, microwave detection, energy harvesting, miniaturized electronic components, bolometers, and thermal detectors. In this paper, a new MA has been provided. The proposed MA is a microwave structure consisting of a network of four split ring resonators (SRRs) of magnetic resonance and negative permeability (  0): one central SRR has a triangular shape and three other SRRs have a square shape and the same dimensions. All SRRs are printed on the upper surface of the FR_Epoxy substrate (r  4.4; tg  0.02), its dimensions are chosen to obtain the resonance at the X-band frequency. To eliminate transmission, we add a copper conductive metal plate that will be etched on the upper face of the same substrate. The main advantage of this study based on the proposed structure is that it is possible to control its absorption percentage for X-band radar applications.
