| 摘要 | We propose a nanoring array structure backed by a metal mirror to achieve perfect infrared absorber with absorption as high as 99:99%. The frequency of the absorption peak strongly depends on the refractive index surrounding the structured surface. This novel feature can be used as plasmonic sensor for refractive index measurement. This plasmonic sensor possesses sensitivity of 600 nm/RIU and the gure of merit can be 180. Due to the high sensitivity and simple sensing scheme, the sensing strategy can nd potential applications in nonlaboratory environments. |
