Spectrum Absorbency of Metamaterial Perfect Absorber

open access: yesThe International Journal of Integrated Engineering, 2022
A triple-band metamaterial perfect absorber was introduced. The single and simple structure based on gold-bar shaped was designed on the 0.018λ Taconic TLY-5. The gold-bar shaped was designed horizontal initially was then being rotated anti-clockwise from0oto 90oto analyze and understand the change of absorption graph.

Broadband metamaterial absorber based on hybrid multi-mode resonance in mid-wave and long-wave infrared region

open access: yesResults in Physics, 2022
The infrared radiation of the target and scene needs to be transmitted through the surface atmosphere, and it can be detected by infrared thermal imaging equipment. The mid-wave infrared band (MWIR, 3–5 μm) and the long-wave infrared band (LWIR, 8–14 μm)
