摘要：

We systematically analyzed, designed, fabricated, and measured a three-layer perfect metamaterial-inspired absorber based on the double split-serration-rings (DSSRs) structure in this communication. The equivalent circuit model was presented to demonstrate the absorbing mechanism. The characters of polarized-insensitivity, wideband, and multiband absorption for the absorber were illuminated by the angular absorptions and surface current distributions. Transformation from wideband absorption with a relative bandwidth of 93.5% from 5.34 to 14.72 GHz, of which the absorptivity was larger than 90%, to multiband absorption was obtained by rotating DSSR-II of 90.. Two absorber prototypes with a thickness of 3.6 mm had been easily implemented using the common printed circuit board fabrication techniques and measured in a microwave anechoic chamber. Simulated and experimental results indicated that the perfect metamaterial-inspired absorber performed wideband and multiband absorption when DSSRs were perpendicular and parallel to each other, respectively.
