摘要：

In this paper, based on the interference theory, the novel binary-structural metamaterial absorber (BMA) using single low-permittivity all-dielectric resonance surface (ADRS) was designed and fabricated. The optimized BMA exhibited three strong absorption peaks at 13.332 GHz, 16.722 GHz, and 17.34 GHz, respectively. The resonance and absorption mechanisms of the BMA were explained via relative impedance analysis, distributions of power loss density and field analysis. Meanwhile, the influences of absorption properties on structure parameters of ADRS were studied. It can be discerned that the three resonance peaks can be owed to electric-resonance of ADRS, and the magnetic-field distributions at resonance frequencies were determined by the ADRS structure. The simulated results were well agreed with the measured one. The current design that employed the low-permittivity ADRS instead of conventional metal resonance surface or high-permittivity ADRS, dramatically simplified metamaterial designs. © 2019,Materials Review Magazine.
