“…Subsequently, equivalent circuit model of the proposed absorber is drawn with the help of surface current distributions and electric field distributions. The comparison between proposed absorber and other available designs in References are given in Table . From Table 1, it is confirmed that the proposed design in very prominent structure in terms of size, thickness, high peak absorption, and ease of fabrication.…”

“…6 Nowadays, microwave absorbers have been extensively investigated from few gigahertz to optical frequency ranges for various potential applications. In the past few years, significant research has been carried out in the design of single band, 7 dual band, [8][9][10] and multiband. [11][12][13][14][15][16] Author Dincer et al 7 analyzed the properties of single band absorber theoretically, numerically, and experimentally.…”

“…However, the large electrical footprint and thickness of the absorber will restrict their application, where confined and flexible geometries are required. Further, Jain et al, presented a single band metamaterial absorber having small dimensions. However, the structure proposed is polarization insensitive in nature but no equivalent circuit modeling is illustrated for better insight of the design.…”

This article reports a compact ultrathin metamaterial absorber with three resonances in S‐band, X‐band, and Ku‐band. The geometry of the proposed absorber consists of a square ring, a splitted square ring, and a plus shaped resonating structure. The plus shaped structure is enclosed within a split ring resonator and it is further enclosed by an outer square ring. The proposed absorber is fabricated on a low cost FR4 substrate of thickness 1 mm that is, 0.011 λlowest (where, λ is the lowest resonating frequency). The size of unit cell is 10 × 10 mm2. It exhibits 99.6%, 99.1%, and 99.1% absorption at 3.4, 9.6, and 13 GHz, respectively. Moreover, the physical insight of the design is explained by surface current distribution and equivalent circuit analysis. Stability of the proposed design is validated with different incident (for transverse electric (TE) and transverse magnetic (TM) modes) angles and different polarization angles. Finally, a prototype of the absorber is fabricated and validated experimentally.
