“…Besides, a THz MA based on a MIM‐typed configuration consisting of a SRR, a dielectric layer, and a metallic mirror was reported. [ 475 ] It is found that the absorbance of the suggested device could be dynamically controlled by replacing the metallic mirror with VO 2 by modifying its conductivity through the optical pumping power.…”

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.

“…The initial research on metamaterial absorbers focused on investigating the capability to perfectly absorb electromagnetic waves at their resonant wavelength [29]. The resonant wavelength could span from the MHz to THz range [30,31]. However, the limitations of a single absorption peak led to the proposal of metamaterial structures with multiple absorption peaks across different frequency ranges [32].…”

Metamaterial absorbers have garnered significant interest due to their unique electromagnetic properties, which facilitate the efficient absorption of electromagnetic radiation in a specific frequency range or multiple frequency ranges. The metamaterial absorbers are designed based on artificially engineered structures that enable tailored absorption properties. These structures might include multiple resonances or incorporate electrical resistive components to achieve broadband absorption. This review paper provides a comprehensive analysis of the progress made in the field of the bandwidth of metamaterial absorbers, encompassing the underlying design principles, key performance characteristics, diverse applications, and perspectives for further research. The paper draws to a conclusion by outlining the potential future directions for further advancements in this exciting area of research, and highlighting the challenges that need to be addressed for the widespread adoption of metamaterial absorbers.

“…For example, modulation of the reflectance is accomplished by shifting the resonance less than 20% in frequency [35]. On the other hand, temperature modulation method offers superior advantages, such as wide-range tunability and ability to integrate with electric or thermal modules for device application [36].…”
