“…However, their performance has often been angle-and polarizationdependent, with a relatively narrow absorption bandwidth, due to the resonant behavior of metamaterial elements. Since modern practical applications require more sophisticated characteristics, such as larger bandwidths or multiple bands of operation as well as wide-angle and polarization-independent responses, a significant research has been triggered -and yet to be expected -for the improvement of these absorbers' overall behavior [10][11][12][13][14][15][16][17][18][19]. Apparently, this is a critical issue for various electromagnetic interference/electromagnetic compatibility (EMI/EMC) problems, like radar-cross section minimization from airplanes, steamboats and other vehicles, EMI protection owing to mobile phones and local area networks, light-trapping structures for photovoltaic systems or terahertz imaging devices [20][21][22][23][24][25].…”

Abstract-The systematic design of size-confined, polarizationindependent metamaterial absorbers that operate in the microwave regime is presented in this paper. The novel unit cell is additionally implemented to create efficient multi-band and broadband structures by exploiting the scalability property of metamaterials. Numerical simulations along with experimental results from fabricated prototypes verify the highly absorptive performance of the devices, so developed. Moreover, a detailed qualitative and quantitative analysis is provided in order to attain a more intuitive and sound physical interpretation of the underlying absorption mechanism. The assets of the proposed concept, applied to the design of different patterns, appear to be potentially instructive for various EMI/EMC configurations.

Cross-resonator metamaterial absorbers (MMA) have been widely investigated from microwave to optical frequencies. However, only part of the factors influencing the absorption properties were analyzed in previous works at the same time. In order to completely understand how the spacer thickness, dielectric parameter and incidence angle affect the absorption properties of the dual-band MMA, two sets of simulation were performed. It was found that with increasing incident angles, the lowfrequency absorption peak showed a blue shift, while the high-frequency absorption peaks showed a red shift. However, with the increase in spacer thickness, both of the absorption peaks showed a red shift. By using the reflection theory expressions, the physical mechanism of the crossresonator MMA was well explained. This method provides an effective way to analyze multi-band absorber in technology.

“…Metamaterial absorbers (MAs) have attracted considerable interests due to their unique properties such as high absorption and ultrathin thickness [1][2][3]. In recent years, the design of MAs with nearunity absorbance has been proposed at microwave and terahertz bands.…”

Abstract-We present the design, characterization, and experimental verification of a dual-band metamaterial absorber (MA) in the microwave frequencies. The proposed MA consists of a metallic gammadion-shaped structure and a complete metal layer, separated by a dielectric spacer. The results show that the proposed MA has two absorption peaks at nearly 5.6 GHz and 6 GHz with absorption rates of 97% and 99%, respectively. The interference theory is used to investigate the physical mechanism of the proposed MA. The experimental results are in good agreement with the theoretical predictions. Furthermore, it is verified by simulations that the absorption of the proposed MA is almost insensitive to the incident wave polarization and oblique incident angle for the both TM and TE modes. This MA has broad prospect of potential applications.
