Paper Abstract

We report a dual-band perfect absorber based on nanodisk array for sensing application in the visible region. Due to the excitation of the magnetic resonance mode, a narrow band absorption peak appears and the absorption rate is greater than 99.9%. The other is due to the excitation of local surface plasmon resonance mode, exhibiting broadband absorption characteristics, and the absorption value is greater than 80%. This structure has a wide angular range absorption characteristic. Finally, we calculated the sensing performance of the structure with refractive index ranging from 1.33 to 1.37. The refractive index sensitivity is 250 nm/RIU and 170 nm/RIU. Therefore, our research provides an important theoretical guidance for narrow-band absorption in the visible region for sensing measurements. This has important application prospects in imaging, sensing and optoelectronic devices.
