Abstract
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.
