This study proposes an ultra-wideband (UWB) metamaterial absorber based on dual-square
ring (DSR) microstructures from the visible to the far-infrared region. The simulation results …

Metasurfaces with sub‐wavelength nanoscale features have emerged as a platform to
achieve desirable electromagnetic responses. However, it remains technically challenging …

In contrast to conventional emitters fashioned from traditional materials, tunable thermal
emitters exhibit a distinct propensity to fulfill the demands of diverse scenarios, thereby …

In recent years, broadband absorbers in the long-wave infrared (LWIR) spectrum have
shown great scientific value and advantages in some areas, such as thermal imaging and …

In this paper, we propose and demonstrate a spectrally selective radiation infrared stealth
metafilm based on a simple bilayer structure. Specifically, we use the common inexpensive …

In this work, a 3-5 μm mid-infrared broadband perfect absorber is proposed. The proposed
absorber is only composed of an aluminium oxide (Al 2 O 3) dielectric layer on the top, a …

In this paper, a dynamically tunable and switchable perfect infrared absorber is put forward,
which is composed of a gold ring array, an indium tin oxide (ITO) layer, an alumina (Al 2 O 3) …

Metasurfaces have emerged as a unique group of two-dimensional ultra-compact
subwavelength devices for perfect wave absorption due to their exceptional capabilities of …

We designed a four-layer structured absorber (Ti-Si-SiO_2-Ti) in the ultra-long-wave infrared
band. The paper applies the bare Ti-SiO_2-Si film to determine the approximate target band …

Perfect infrared absorber with controllable working bandwidth is proposed, consisting of a
continuous Au film, a FR-4 spacer, multilayer Dysprosium-doped cadmium oxide (CdO: Dy) …
