Metamaterials have drawn a great attention in recent years because of their unnatural electromagnetic properties such as backward wave propagation, negative refractive index and phase velocity. Therefore, they introduce a different perspective on lenses, antennas, sensors and electromagnetic wave absorber applications. Due to their simple design, easy fabrication process, perfect and broadband absorption features as well as tunable and controllable absorption characteristics, they become a good candidate for stealth applications. In this paper, design, simulation, fabrication and measurement of a dual-band polarization independent metamaterial absorber are presented in the microwave regime. The proposed metamaterial absorber has two distinct absorptive peaks 7.90 GHz and 8.90 GHz with top absorption levels of 99.9 % and 99.3 %, respectively. The measurement results are good agreement with the simulations for different polarizations of electromagnetic waves. Depending on these results, it is possible to say that, metamaterial absorbers can find a promising future in stealth technology applications.
