摘要

本文采用金属-绝缘体-超表面（MIM）堆叠结构，实现了一种有效的长波红外超宽带吸收体。这种吸收体在8-14µm的波长范围内表现出90%的平均吸收率和高达97.1%的最大吸收率。研究发现，这种性能是通过三种模式组合实现的。超宽带调平吸收体由于其几何对称性而与偏振无关。吸收特性可以通过三角形单元的参数来控制。它在红外探测和成像等许多应用中具有巨大的潜力。

Infrared Absorber Leveling in Ultra-Wideband by Using Hybrid Plasmonic Structure

In this paper, an effective ultra-broadband absorber in long-wavelength infrared is achieved by a metal-insulator-metasurface (MIM) stacked structure. This absorber exhibits an average absorption of 90% at wavelengths ranging from 8 to 14 µm and a maximum absorption rate of up to 97.1%. It is found that the performance is achieved by three mode combinations. The ultra-broadband leveling absorber is to be polarization-independent due to its geometrical symmetry. The absorption property can be controlled by the parameters of the triangle unit. It has great potential in many applications such as infrared detection and imaging.

期刊介绍： Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
