摘　　要：热辐射是物理实验研究的一个重要方面。基于金属-介质-金属“三明治”式微纳米结构,制作了一种超材料光谱选择性窄带热辐射源。测量结果表明,该辐射源能够将热辐射能量集中在9.03μm波长附近,峰值发射率高达98.0%,发射带宽仅为1.58μm。实验还展示了这种热辐射源峰值辐射波长的灵活调控特性。Thermal radiation is an important aspect of experimental physics research.A spectrally selective thermal radiation source was fabricated based on metal-dielectric-metal“sandwich”metamaterial.The manufactured metamaterial source exhibited desirable thermal radiation feature according to experimental results,which revealed that thermal radiation energy has been focused within a narrowband around the designed wavelength of 9.03μm with peak emissivity up to 98.0%and bandwidth of 1.58μm.
