Abstract:In this paper, a novel broadband flexible metamaterial absorber, which is based on high impedance surface (HIS), has been investigated. The polarization-insensitive absorber can suppress the backward RCS by about 10 dBm(2). Numerically simulated results indicate that the HIS metamaterial absorber (HIS-MA) obtains 11.14 GHz wide absorption from 6.86 to 18 GHz with the absorption over 90%. The results of experiment coincide with simulations, which prove the feasibility of HIS-MA. The flexibility and absorption performance of the HIS-MA is demonstrated by simulating and measuring the absorptivity as the absorber is bended on cylinders, which can obtain some novel properties. The simulated results of bistatic RCS showed that the bistatic RCS of HIS-MA bended on a cylindrical object is reduced by nearly 10 dBm(2) compared with the conventional planar HIS-MA. The proposed absorber has more advantages in conformal applications than ordinary rigid absorber in its stealth property.
