为了充分利用太阳能,提出一种基于超材料纳米结构所设计的超宽带吸收器,该超材料纳米结构由SiO2-Ti空心十字架的周期性阵列和SiO2-Ti底膜组成。该吸收器结合表面等离子体的共振与金属绝缘体—金属法布里-珀罗(FP)腔诱导的共振,实现对太阳光近乎完美的吸收。经仿真实验证实,在波长为400~2500 nm的范围内,平均吸收率达到了97.4%,并且吸收峰值高达99.9%。通过分析在TE和TM偏振波斜入射时的吸收性能,证明了器件对偏振和入射角度并不敏感。此外,还详细讨论了各种金属材料和不同几何参数对吸收性能的影响。

In order to make full use of solar energy,an ultra-wideband absorber based on metamaterial nanostructure is proposed,which consists of periodic array of SiO2-Ti hollow cross and SiO2-Ti substrate.The absorber combines the excitation of surface plasmon resonance with the resonance induced by metal-insulator-metal Fabry-Perot (FP) cavity to achieve near-perfect absorption of sunlight.In the wavelength range of 400 nm to 2500 nm,the average absorption rate reaches 97.4%,and the peak absorption is as high as 99.9%.By analyzing the absorption performance of TE and TM polarized waves at oblique incidence,the device is not sensitive to polarization and angle.In addition,the effects of various metal materials and different geometric structures on the absorption properties is discussed in detail.
