Chain-type metamaterial absorber for multi-mode polarization-sensitive infrared wavelengths

Abstract

The present invention discloses a multi-mode polarization-sensitive infrared band metamaterial absorber based on a chain-type structure, which comprises a metal resonator, a dielectric layer, and a metal reflection layer arranged sequentially from top to bottom. The metal resonator and the metal reflection layer form a resonant cavity for capturing incident light. The metal resonator comprises resonant units arranged periodically. Each resonant unit comprises sequentially connected resonant groups. Each resonant group comprises a central metal block, a first metal block, a second metal block, a third metal block, and a fourth metal block. The first metal block and the third metal block are disposed on one side of the central metal block and are in contact therewith. The second metal block and the fourth metal block are disposed on another side of the central metal block and are in contact therewith. The present invention achieves a multi-mode, broadband, polarized absorption response.
