WebNov 27, 2024 · In this paper, we design a near perfect absorber that is highly tunable, angle insensitive, and has polarization independence for LWIR. By using multi-mode localized surface plasmon resonance (LSPR) of a surface metal structure, the absorber achieves a very high absorption average of 99.7% in wavelengths from 9.7 μm to 12.0 μm. WebMay 10, 2013 · An absorbance of more than 90% is experimentally realized and the resonance occurs in the space between the tines. Since a continuous layer of metallic thin …

WebAug 2, 2024 · The strong absorption suggests the achievement of perfect absorber platform via the common metal grating cooperated with the optical dielectric nano-cavity. In contrast to the relatively broad bandwidth of 22 nm for the first absorption peak, a narrow linewidth with the value down to 1.6 nm is achieved for the second peak. WebAug 7, 2013 · In this way the heat transferred from the absorbed energy can be dissipated easily. Since a continuous metallic thin film covers the structure, it is perfectly thermo- … WebOct 20, 2024 · We developed a flexible perfect absorber based on a thin-film nano-resonator, which consists of metal–dielectric–metal integrated with a dielectric overlay. The proposed perfect absorber exhibits a high quality (Q-)factor of ~ 33 with a narrow bandwidth of ~ 20 nm in the visible band. how to heal a poison ivy rash
