“…These design methods are widely used in the fabrication of BMAs because of their excellent characteristics, such as ease to manufacture, low cost, simple structure, broadband with high absorption, etc. According to the number of subresonators in the top patterned layer or surface structure of MAs, there are three common planer design strategies, which are 1) single resonator design approach, [271,[339][340][341][342][343] 2) combined design strategy of multiple sub-resonators, [272,344,345] and 3) fractal design approach. [273,[346][347][348][349] Single resonator design approach means that the unit cell (UC) of the surface structure of BMAs contains only one (or single) patterned resonator.…”

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.

“…Novel metamaterial absorbers (MAs), which work on the principal of resonance, have been explored for use with wireless communication devices (emitters, filters, sensors, photodetectors, photovoltaic solar cells, and infrared camouflage) [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. Significant work on MA designs is available in the literature for microwave, terahertz, visible, and ultraviolet frequencies [ 13 , 14 , 15 , 16 , 17 , 18 ]. On the contrary, 5G and especially 24 GHz and 28 GHz bands are relatively unattended so far, in this regard [ 19 , 20 , 21 , 22 ].…”

Fifth generation (5G) communication systems deploy a massive MIMO technique to enhance gain and spatial multiplexing in arrays of 16 to 128 antennas. In these arrays, it is critical to isolate the adjacent antennas to prevent unwanted interaction between them. Fifth generation absorbers, in this regard, are the recent interest of many researchers nowadays. The authors present a dual-band novel metamaterial-based 5G absorber. The absorber operates at 24 GHz and 28 GHz and is composed of symmetric meander lines connected through a transmission line. An analytical model used to calculate the total number of required meander lines to design the absorber is delineated. The analytical model is based on the total inductance offered by the meander line structure in an impedance-matched electronic circuit. The proposed absorber works on the principal of resonance and absorbs two 5G bands (24 GHz and 28 GHz). A complete angular stability analysis was carried out prior to experiments for both transverse electric (TE) and transverse magnetic (TM) polarizations. Further, the resonance conditions are altered by changing the substrate thickness and incidence angle of the incident fields to demonstrate the functionality of the absorber. The comparison between simulated and measured results shows that such an absorber would be a strong candidate for the absorption in millimetre-wave array antennas, where elements are placed in proximity within compact 5G devices.

“…In 2008, Landy et al introduced the first perfect MMA in which electric and magnetic resonances were generated in a narrow frequency band around 11.65 GHz 9 . MMAs have certain advantages compared with conventional absorbers 10 – 13 like ferrite 14 and Salisbury screen absorbers 15 . For instance, MMA can achieve a high level of absorptivity in spite of a thin substrate.…”

Ultrawide-angle electromagnetic wave absorbers with excellent mechanical properties are required in many diverse applications such as sensing, and stealth technologies. Here, a novel 3D reconfigurable metamaterial absorber (MMA) consisting of honeycomb and VO2 films is proposed. The proposed MMA exhibits a strong absorptivity above 90% in the widest incident angle up to $$87^\circ $$ 87 ∘ for TM- and TE polarized oblique incidences for THz wave propagating in yoz-plane. Under normal incidence, when VO2 films are in the insulating state, the proposed absorber exhibits high absorptivity in the frequency band of 1–4 THz. By increasing the temperature of the whole structure, the structural transformation of VO2 occurs and turns into the metallic phase. We have shown that under oblique incidence, the ohmic losses of VO2 films especially those parallel to the direction of the incident electric field are the most important absorption principles of the proposed MMA. Due to the ultra wide-angle absorption (angular stability) and mechanical performance, it is expected that the presented MMA may find potential applications, such as camouflage technologies, electromagnetic interference, imaging, and sensing. To the best knowledge of authors, the proposed MMA configuration exhibits the absorptivity in the widest incident angle ever reported.
