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 9.03 μｍ波长附近，峰值发射率高达 98.0 ％，发射带宽仅为 1.58 μｍ。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。

Abstract:

Thermal radiation is an important aspect of experimental physics research.A spectrally selectivethermal radiation souree was fabricated based on metal-dielectrie-metal “ sandwich "metamaterial. "hemanufactured metamaterial source exhibited desirable thermal radiation feature according to experimental results , which revealed that thermal radiation energy has been foeused within a narrowband around the designedwavelength of 9.03 um with peak emissivity up to 98.09 and bandwidth of 1.58 μm.

Key words: thermal radiation metamaterials narrowband
