摘要

中红外和远红外波段的宽带吸收在科学技术上具有重要意义。本文提出了一种中远红外超材料吸收体，时域有限差分仿真计算表明，其吸收率在6.73 ~ 16.65 μm波段，平均吸收率为96.01%。同时，虽然吸收性能取决于偏振态和入射角，但在较宽的角度范围内表现出相对稳定性。利用时域有限差分电磁场分析可视化吸收器内部的电场和磁场强度分布，可以知道吸收器的共振模式有表面等离子体共振（SPR）、局域表面等离子体共振（LSPR）和法布里-珀罗腔共振。同时，调整吸收层厚度和周期几何参数可以优化吸收性能。此外，不同的微观结构和不同的顶部材料对吸收器的吸收率也有影响。该吸收剂在热电器件、红外成像和热探测等方面具有很高的实用价值。

Infrared band ultra wideband metamaterial absorption device based on cylindrical multiscale resonator

Mid-infrared and far-infrared regions broadband absorption is of great significance in science and technology. In this paper, we put forward a mid-far infrared metamaterial absorber, and Finite-Difference Time-Domain simulation calculation shows that the absorption rate in the 6.73-16.65 μm band, with an average absorption rate of 96.01%. At the same time, although the absorption performance depends on the polarization state and the incidence angle, it shows the relative stability in a wide angle range. Using the FDTD electromagnetic field analysis visualize the electric and magnetic field intensity distributions within the absorber, it can be known that the resonance mode of the absorber has surface plasmon resonance (SPR), localized surface plasmon resonance (LSPR), and Fabry-Perot cavity resonance. Meanwhile, adjusting the absorption layer thickness and the periodic geometry parameters can optimize the absorption performance. In addition, different microstructures and different top materials also have an influence on the absorption rate of the absorber. The absorber has high practical value in thermoelectric devices, infrared imaging and thermal detection.

期刊介绍： Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
