Abstract
Microwave absorbers have been attracted much more attentions in both military and civil fields nowadays. In this paper, we present a multi-band metamaterial absorber with the excellent performances of wide-angle incidence and polarization insensitivity. The designed absorber is composed of two distinct metallic layers separated by a dielectric substrate. The simulated absorptions of the absorber are 92.9%, 92.5% and 98.5% at 5.92 GHz, 6.12 GHz and 8.54 GHz, respectively. The microwave experiments are performed to verify the simulations, and the measured results are in agreement with the simulations. Surface current distribution is illustrated to investigate the physics of absorption. We believe that the designed absorber has numerous potential applications in stealth, sensing, electromagnetic absorption and thermal detectors.
