摘要/Abstract

摘要： To promote the application of far-infrared technology, functional far-infrared devices with high performance are needed. Here, we propose a design scheme to develop a wide-incident-angle far-infrared absorber, which consists of a periodically semicircle-patterned graphene sheet, a lossless inter-dielectric spacer and a gold reflecting film. Under normal incidence for both TE- and TM-polarization modes, the bandwidth of 90% absorption of the proposed far-infrared absorber is ranging from 6.76 THz to 11.05 THz. The absorption remains more than 90% over a 4.29-THz broadband range when the incident angle is up to 50° for both TE- and TM-polarization modes. The peak absorbance of the absorber can be flexibly tuned from 10% to 100% by changing the chemical potential from 0 eV to 0.6 eV. The tunable broadband far-infrared absorber has promising applications in sensing, detection, and stealth objects.
