摘要

我们从理论上提出了硅基同心管元材料吸收体，由连续的本征硅和掺杂硅(D-Si)层组成的同心管。我们提出的结构在3 ~ 7 μm的中红外波长范围内具有宽带性能，在s偏振入射光的情况下吸收率大于0.89。提出的设计为实现中红外光探测和中红外热收集应用的Si/D-Si同心管超材料吸收器提供了新的途径。

Study of the Absorption Spectrum in Mid-IR Range Using Concentric Tubes Metamaterial Structures

We theoretically propose Si based concentric tubes meta material absorber, comprised from consecutive concentric tubes of intrinsic Si and doped Si (D-Si) layers. Our proposed structure exhibits broadband performance within the mid IR wavelength range extending from 3 to 7 μm with an absorption more than 0.89 in case of S-polarized incident light. The proposed design reveals new avenues to realize Si/D-Si concentric tubes metamaterial absorber for mid IR photo detection and mid IR thermal harvesting applications.
