“…The comparison of the proposed FSS-based rasorber with the previously reported rasorbers are shown in Table 4. The proposed rasorber is polarisation-insensitive, single layer thin structure compared with other reported rasorbers [25,26,29]. The proposed rasorber also possess better insertion loss at two transmission bands in comparison with the other rasorbers reported in [25,29].…”

“…Recently several FSS-based rasorbers have been reported [22,[25][26][27][28][29], in which the transmission window is achieved in addition to the broadband absorption. A novel dual-polarised bandabsorptive FSR reported in [25] utilises the combination of lossy and lossless layer to achieve the low frequency transmission window below 1.54 GHz along with the broadband absorption from 4.8 to 6.81 GHz.…”

“…A polarisation-insensitive rasorber with absorption band within two transmission bands is reported in [28], with an absorption window from 4.08 to 9.22 GHz and a dual pass band at around 3.66 and 9.28 GHz. A polarisation-sensitive dual-band FSR is reported in [29] in which two transmission windows are at around 7.2 and 13.05 GHz along with two broad absorption bands in the range of 4.02-6.27 GHz and 8.21-12.02 GHz. The reported FSR designs [22,[25][26][27][28][29] are the multi-layer structures utilising the concept of circuit analogue absorbers in which the lumped resistors are mounted in the FSS structure for obtaining the broadband absorption.…”

In this study, a frequency selective surface (FSS)‐based rasorber has been proposed by combining the designs of split‐ring absorber and dual bandpass FSS, which are printed on the front and backside of 0.8‐mm thick FR‐4 substrate, respectively. The proposed FSS‐based rasorber is a thin single layer structure and also exhibits the polarisation‐insensitive behaviour due to its four‐fold symmetry. The split‐ring structure at the front contributes to the resonant absorption at 6.2 GHz, while the bandpass FSS structure at the backside provides two transmission windows at 3.1 and 8.4 GHz, respectively. The parameters of the design are optimised such that at the absorption frequency, the bandpass FSS acts as a complete metallic ground. The operating principle of the proposed rasorber is analysed using an equivalent circuit model. The effects of design parameters on the performance of the rasorber are studied, and accordingly an optimum range of lower and upper transmission bands with respect to the absorption band are determined. A 21×21 array of the proposed rasorber unit cell is fabricated, and the results are experimentally verified.

“…A-T-A type) were also presented [8]- [17]. In addition, rasorbers with dual transmission bands were also experimentally investigated by M. Guo et al [26], [27]. Compared with the A-T and T-A types with a single transition region between transmission and absorption bands, the A-T-A or dual-band rasorbers exhibit more transition bands with unacceptable absorption or transmission performance.…”

An active band‐notched frequency selective absorber (BNFSA) with switchable notch band is proposed in this article. The BNFSA is a two‐layer structure composed of a lossy layer at the top and a ground plane at the bottom, separated by an air spacer. The element of the lossy layer is a lumped‐resistor‐loaded metallic dipole with a parallel LC resonance structure, which is realized by complementary n‐shaped resonator (CnR) inserted in the center, and PIN diode is welded at two arms of CnR. The bias circuit printed on the back of the substrate of the lossy layer connects to anode and cathode of the diode by via hole and isolates by the inductor. Simulation results show that the notch bands are located at 4.50 and 6.81 GHz when the diode sets to ON and OFF, respectively. To validate the performance of switchable BNFSA, the prototypes are fabricated and measured, reasonable agreement between simulated and measured results is obtained.
