Multiband metamaterial selective absorber for infrared stealth

Applied Optics, 2020
Nanostructured selective absorbers have widespread applications ranging from artificial color to thermophotovoltaics and radiative cooling. In this paper, we propose a metamaterial selective absorber with a metal–insulator–metal structure for infrared stealth.

All-metal frequency-selective absorber/emitter for laser stealth and infrared stealth

Applied Optics, 2018
In this paper, an all-metal nanostructure is designed with a large frequency ratio (∼6) and a large bandwidth ratio (∼32), and consists of period slit-box cavities and nanodisk clusters. It is a nearly perfect absorber at 1.064 μm to achieve laser stealth, a frequency-selective emitter with low emissivity in wavelength ranges 3-5 and 8-14 μm to achieve

Broadband and Ultrathin Infrared Stealth Sheets

Advanced Engineering Materials, 2018
To effectively hide objects and render them invisible to thermographic detectors, their thermal signatures in the infrared (IR) region of the spectrum may be concealed. However, to conceal broadband spontaneous thermal emission of objects, covering the mid‐ and long‐IR is a major obstacle.
