Abstract

In this paper, a near-perfect terahertz absorber is proposed. Based on the multi-layer resonances, the meta-surface has obtained absorbing rate of more than 90% from 2.7THz to 4.38THz. Since the strict center symmetry of the structure, the same absorbing rate and bandwidth can be maintained for any polarization angle. In addition, while the incident angle is 40 degrees, the structure can hold the original bandwidth, and the absorbing rate is approximately maintained above 80%.
