“…[42] In order to increase the bandwidth of MMPAs, R is usually adjusted to yield a flatter, lower Q-factor. [42][43][44][45] Therefore, with a simple design, perfect absorption can be easily achieved at a single wavelength, but the design becomes complicated and difficult for absorbers with perfect absorption while achieving broadband absorption. Substantial progress has been made in developing broadband metamaterial perfect absorbers (BMMPAs), but the field remains immature.…”

The recent rise of metamaterials opens new opportunities for absorbers due to their designed electrodynamic properties and effects, allowing the creation of materials with effective values of permittivity and permeability that are not available in naturally occurring materials. Since their first experimental demonstration in 2008, recent literature has offered great advances in metamaterial This article is protected by copyright.

Broadband absorbers are indispensable in thermophotovoltaics, photodetection, bolometry and manipulation of mechanical resonances. Although it is easy to obtain MMPA with single band or above, achieving broadband MMPA (BMMPA) remains a challenge due to the intrinsically narrow bandwidth of surface plasmon polaritons, localized surface plasmon resonances generated on metallic surfaces at nanoscale or high Q-factor in GHz region. To guide future development of BMMPA, recent progress is reviewed here: the methods to create broadband absorption and their potential applications. The four mainstream methods to achieve BMMPA are introduced, including planar and vertical element arrangements, their welding with lumped elements and the use of plasmonic nanocomposites, accompanied by the description of other, less common approaches. Following this, applications of BMMPA in solar photovoltaics, photodetection, bolometry and manipulation of mechanical resonances are reviewed. Finally, challenges and prospects are discussed.

Toward an Ultra-Wideband Hybrid Metamaterial Based Microwave Absorber

In this paper, we propose a novel design of an ultra-wideband hybrid microwave absorber operating in the frequency range between 2 GHz and 18 GHz. This proposed hybrid absorber is composed of two different layers that integrate a multiband metamaterial absorber and a lossy dielectric layer. The metamaterial absorber consists of a periodic pattern that is composed of an arrangement of different scales of coupled resonators and a metallic ground plane, and the dielectric layer is made of epoxy foam composite loaded with low weight percentage (0.075 wt.%) of 12 mm length carbon fibers. The numerical results show a largely expanded absorption bandwidth that ranges from 2.6 GHz to 18 GHz with incident angles between 0° and 45° and for both transverse electric and transverse magnetic waves. The measurements confirm that absorption of this hybrid based metamaterial absorber exceeds 90% within the above-mentioned frequency range and it may reach an absorption rate of 99% for certain frequency ranges. The proposed idea offers a further step in developing new electromagnetic absorbers, which will impact a broad range of applications.

A new polarization independent broadband metamaterial absorber (MA) structure based on split ring resonators which are loaded with lumped elements and via connection lines is proposed. The designed structure shows a perfect absorption between 4 and 16 GHz which is validated by simulation studies. Experimental study is only made for the structure that has no via connections and no the lumped element resistors to show the importance of these entities in the proposed metamaterial structure. Both numerical and experimental study results show that broadband MA property depends on the resistors and via connections on the proposed structure. By having high absorption in a wideband range which is numerically demonstrated, the proposed structure can be used in energy harvesting or wireless power transfer applications with higher efficiencies.Metamaterials have attracted great attention owing to their unique electromagnetic and optical properties, such as negative refraction 1 and asymmetrical transmission. 2-4 One of the most popular types of metamaterial is metamaterial absorbers (MA) which was initially proposed by Landy et al. 5 in 2008. After that, different types of single band and multi band MA studies were proposed. 6,7 In addition, polarization independent and tunable perfect metamaterial absorbers (PMA) with wide incidence angles were designed in microwave, THz, and optical frequency bands. [8][9][10] Because of the diffraction limitations, traditional absorbers cannot be designed and produced in small dimensions. Since reduction in the electrical thickness of the absorbers is one of the main design inputs, the need for producing these absorbers has emerged. Tao et al. realized a study in which they achieved 96% absorption at 1.6 THz. 11 Metamaterials are also used in many areas including super lenses, 12 invisibility cloaking, 13,14 polarization rotation, 15 sensing applications, 16 antennas and energy harvesting. [17][18][19][20][21] Researchers have been working on bandwidth enhancement and polarization insensitiveness by applying different methods. [22][23][24] These methods can be listed as resistive film placement, loading lumped elements, and using multilayer structures. [25][26][27][28][29][30] In a study conducted by Tang et al., 25 resistive films which were vertically placed on the metal plate were used to increase the bandwidth. In that study, polarization independent MA was designed and its operation between 20 and 55 GHz is demonstrated. In Ref. 26, Mulla et al. obtained a bandwidth increase by using multilayer structure numerically between 624 and 658 THz. Chen et al. designed MA which was composed of a single dielectric substrate, double circular metallic rings and resistive loads operating between 8.87 and 16.47 GHz. In Ref. 27, Chen et al. studied a broadband absorber by using lumped elements and they obtained more than 7 GHz bandwidth with 90% absorption. In Ref. 28, Ding et al. conducted a study for a microwave ultrabroadband polarization independent metamaterial by using periodic array of met...
