“…We start with an existing design which has been proposed by Shang et al [1], comprising of a complex dual-loop absorber illustrated in Fig.1. The conducting strips forming the loop can be segmented into various lengths to introduce multiple resonances.…”

“…The multiple resonances of the system can be adjusted to achieve a wideband performance (as shown in Fig.2). In this work we compare the performances of three different configurations: (a) the original design in [1] which has a resistively-loaded dual-loop (PEC); (b) a modified design with a resistively-loaded dual-loop (lossy with a sheet resistance of 100Ω/□) as shown in Fig.3; (c) a complete dualloop (lossy with a sheet resistance of 100Ω/□) as shown in Fig.4.…”

“…In recent years FSS-based absorbers have drawn the attention of a number of researchers [1,2]. Such absorbers are typically realized in two different ways by using (i) lossy FSSs, with varying sheet resistance; and unit cells with perfectly conducting strips with resistive inserts.…”

“…And the several absorption peaks with low Q factor finally overlapped together contributing highly effective and broadband absorption. Meanwhile, the materials with strong ohmic loss, such as resistive patch, can also be introduced here to construct broadband MA in electromagnetic wave [23][24][25][26][27][28][29]. Compared with the aforementioned MA based on metal-dielectric-metal configuration, resistive MAs were easy to achieve highly effective and broadband absorption as well as other advantages, such as light-weight, low cost, and easy fabrication.…”

Abstract:Resistive patch array incorporating with metallic backplane provided an effective way to the achievement of broadband metamaterial absorbers(MAs). When loading metallic metamaterial to resistive MA, the outstanding construction helps realize more flexible and diversified forms of broadband absorption. In this paper, we attempted to load metallic resonators(MRs) to resistive MA in the three-dimensional construction, which benefits further enhancement of lower-frequency absorption. Simulation showed that the partial absorption band was separated to lower frequency, while the rest of broadband absorption was unaffected. Meanwhile, after combining multi-unit of the proposed MAs, the stair-stepping broadband absorption was also achieved. At last, three samples were fabricated. The agreements between simulations and experimental results demonstrated that resistive MA loaded with MRs provided an effective way for further enhancement of lower-frequency absorption with almost no change of the absorbing structure and areal density. Thus, it is worthy to expect a wide range of applications to emerge inspired from the proposed attempt.

“…Li et al [10] showed that the resistive treble square FSS with thickness 0.193λ could be used for 10 dB RCS reduction for a relative bandwidth of 92.2%. A 10 dB reflectivity reduction for a fractional bandwidth of 126.8% with thickness 0.088λ was realized for a double square loop array with lumped resistors [11]. Triple band HIS absorber with periodic diversified impedance was used for 42% increase in 90% of absorption bandwidth [12].…”

Abstract-A detailed study on the performance of a high impedance surface on lossy dielectric is presented in this paper. It is observed that the structure, which is an array of square loops on a grounded dielectric, behaves as artificial magnetic condutor, narrowband absorber or perfect electric conductor depending on the dielectric loss. An equivalent circuit modelling is used to theoretically explain how this transition is happening. The observed narrowband absorption (bandwidth = 0.08 GHz) of the thin (0.016λ) lossy dielectric is scalable to different operating frequencies by varying the structure parameters. The simulation studies on the effect of structural and dielectric properties on the characteristics of this HIS are also dealt with in this paper. Experimental investigation is in good agreement with simulated result and equivalent circuit modelling.
