“…Therefore, when the TM wave is incident to the structure, the free electrons on the metal surface resonate with the incident wave, and surface plasmon resonance is generated at the intersection of the medium and the metal. The surface plasmon resonance excitation generates surface plasmon polaritons (SPPs), 44 which interact with the cavity mode resonance at the gap, causing the energy to be localized at the surface of the metal structure and at the air gap, resulting in an enhanced electric field and increased light absorption. As shown in Fig.…”

“…Only a continuous absorption band with high absorbance could ensure the maximum absorption of incident energy. Therefore, BMAs containing both broadband absorption response and near-perfect absorption are rightly applied to energy harvesting applications, which are currently the most widely used in solar energy harvesting [261,[563][564][565][566][567][568][569][570][571][572][573] and microwave energy harvesting.

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.

Compared to traditional bulk counterparts, metasurface absorbers are advantageous in compactness with their ultrathin functional layers down to the nanometer scale. The absorbers possessing properties of large bandwidth and polarization insensitivity are highly required and have been developed for various spectral ranges from ultraviolet to microwave. [5][6][7][8][9][10][11][12] Unlike metasurface absorbers that work in long wavelengths such as mid-infrared [8] or terahertz, [9] obtaining a device to work in the ultraviolet, visible light, or near-infrared (NIR) band will place higher requirements on the feature size of its structures due to the subwavelength working regime of the device. The traditional fabrication process suffers from low efficiency and high cost during the large-area fabrication of the subwavelength structures. Methods, like mask-based fabrication, [13,14] mask-free fabrication, [15,16] and composite methods, [17] are widely investigated to achieve the large-area fabrication of those broadband metasurface absorbers. Generally, multi-layers or complicated structures with an elaborated design are usually required to meet the wide bandwidth absorption demands, whose low-cost and high-efficient fabrication methods are still a long-pending challenge to overcome.A well-known light-driven self-organization phenomenon called laser-induced periodic surface structures (LIPSS) has attracted growing attention due to the advance of mask-free large-area surface patterning ability of subwavelength structures with long-range order. [18][19][20][21] These merits endow this laser nanopatterning technique to be potent for scalable, low-cost, and fast manufacturing of metasurfaces. [22][23][24][25][26] Nevertheless, most LIPSS are usually nanogratings that exhibit an obvious anisotropic property. The fabricated devices with one-dimensional nanogratings are usually polarization-sensitive due to the unidirectional characteristics in structure. [27] Realizing polarization-insensitive absorption through subwavelength gratings (so-called metagratings) can be achieved based on exciting different resonance modes under TE and TM polarizations. [28,29] The structural sizes need to be carefully designed to meet this demand, which makes most of these published works only achievable in design schemes without further research on the fabrication of practical metasurface devices.Subwavelength-structured metasurfaces working in visible and near-infrared bands present a high challenge in large-scale device fabrication. In this study, a scalable, high-efficient, and low-cost laser-induced nanopatterning technique is exploited to fabricate a kind of short-range disordered metagratings, which enables broadband polarization-independent absorption in the visible to near-infrared wavelength. The short-range disorder of the laserinduced nanogratings originates from the laser-induced thermal effect and can be spontaneously organized during laser nanopatterning. The unique disorder can break the unidirectional characteristics of the nanog...
