摘要:

热发射是一种普遍存在的电磁波,在自然界中具有极宽的光谱,控制热发射可用于开发低成本、便捷的红外光源,其波长可在宽范围内调谐,而这是其他光源目前难以实现的。传统超表面通常用于控制光,但缺乏实现复杂发射光谱轮廓和动态调谐的灵活性。在此,我们提出了一种新颖的双层超表面结构,具有两个完全独立的层,以在5-8微米波长范围内实现多峰热发射。模拟和实验表明,这种双层结构可以在不干扰多个谐振模式的情况下实现任意光谱形状。这种独特的配置为热发射工程的进一步探索提供了一个有前景的平台,能够实现光谱控制和动态调谐。

英文摘要:

Thermal emission is a ubiquitous electromagnetic wave with an extreme broad spectrum in nature, and controlling thermal emission can be used to develop low-cost and convenient infrared light sources with wavelength tunable in a wide range that is currently difficult to other sources. Conventional metasurfaces are commonly used to control light but lack the flexibility to achieve complex emission spectral profiles and dynamic tuning. Here, we introduce a novel dual-layer metasurface structure with two completely independent layers to achieve a multi-peak thermal emission within the 5-8 μm wavelength range. Simulations and experiments show that this two-layer structure can achieve arbitrary spectral shapes without interfering with multiple resonant modes. This unique configuration presents a promising platform for further exploration in thermal emission engineering, enabling spectral control and dynamic tuning.
