“…Therefore, the most cost‐effective approach is to omit the metal used to make resonance and the ground plane at the bottom and use only low‐cost dielectrics to make the broadband absorption. [ 318–330 ] Meanwhile, the use of low‐cost dielectric materials could reduce the harm to the environment, thus laying a solid foundation for the preparation of environment‐friendly BMAs.…”

“…For example, by combining several dielectric materials of Ge, zinc selenide, and lead sulfide, a cascaded all‐dielectric multilayer structure of BMAs with an average absorption of 90% within 6.2–7.8 µm was demonstrated. [ 323 ] Besides, due to the single broadband resonance in the high‐loss Fabry‐Perot cavity and the inherent loss property of Ge, a flexible optical BMA with an all‐dielectric multilayer structure was designed with an average absorbance of 97.4% covering the whole visible light. [ 324 ] Due to the excellent physical properties of Ge, all‐dielectric BMAs based on Ge will certainly receive extensive attention.…”

Metamaterial absorbers have been widely studied and continuously concerned owing to their excellent resonance features of ultra-thin thickness, light-weight, and high absorbance. Their applications, however, are typically restricted by the intrinsic dispersion of materials and strong resonant features of patterned arrays (mainly referring to narrow absorption bandwidth). It is, therefore essential to reassert the principles of building broadband metamaterial absorbers (BMAs). Herein, the research progress of BMAs from principles, design strategies, tunable properties to functional applications are comprehensively and deeply summarized. Physical principles behind broadband absorption are briefly discussed, typical design strategies in realizing broadband absorption are further emphasized, such as top-down lithography, bottom-up self-assembly, and emerging 3D printing technology. Diversified active components choices, including optical response, temperature response, electrical response, magnetic response, mechanical response, and multi-parameter responses, are reviewed in achieving dynamically tuned broadband absorption. Following this, the achievements of various interdisciplinary applications for BMAs in energy-harvesting, photodetectors, radar-IR dual stealth, bolometers, noise absorbing, imaging, and fabric wearable are summarized. Finally, the challenges and perspectives for future development of BMAs are discussed.

“…[1,[13][14][15][16][17][18] Comparing to the traditional coatings with low emittance at full infrared waveband, the selective metasurfaces maintain the low observability at atmospheric window and supply efficient radiative heat dissipation to avoid potential thermal instability. [1,[19][20][21][22][23] In addition, selective metasurfaces are promising candidates supporting compatibility with laser stealth, which is important to escape from the detection of multiband seekers such as cameras incorporating mid-infrared (MIR) imaging and near-infrared (NIR) laser active detection. [24] Generally, the simultaneous dual-band responses of metasurfaces can be achieved by reasonably combining different resonant modes.…”

Metasurface-based mid-infrared stealth compatible with visual or laser provide a promising way to increase survivability of military installations. However, current designs of metasurfaces following traditional paradigm suffer from low efficiency on calculating global structural parameters for multispectral requirements and limited thermal radiation engineering. Here, a metasurface with high-performance compatible stealth and effect thermal management is proposed, based on a machine-learning-enabled inverse design approach. The approach can rapidly generate multiple non-unique solutions in global to match the desired spectra in multi-wavebands, utilizing neural networks with physical-based data dimensionality. The finally generated metasurface has low specular reflectance (<0.01) at near-infrared laser wavelength and enhanced broad absorptance peak at 5-8 µm, which is attributed to the reflection splitting effect and infrared plasmonic resonance, respectively. Furthermore, a lowcost fabrication method is developed to produce the metasurface by colloidal lithography. The metasurface is demonstrated to have excellent capability of radiative thermal control and significantly decrease the apparent temperature under thermal imager (>50 °C). This study reveals an opportunity to inversely generate multiple solutions for photonic structures targeting on multispectral responses, in a systematic and efficient manner.

“…This work offers promising advances towards ultimately realizing electrically-injected, silicon-based quantum cascade lasers operating at THz frequencies. Z. Zhao et al propose and study numerically an all-dielectric multilayer material that that absorbs weakly in the 8-14 µm atmospheric window and strongly (up to 95%) in a 1.2 µm wide spectral region outside the atmospheric window [6]. Additionally, the proposed structure depends weakly on polarization.…”
