This paper presents a miniaturized frequency selective rasorber (FSR) with both wide absorption and transmission bands. The proposed FSR consists of a resistive sheet and a band-pass frequency-selective surface (FSS) with non-resonant constituting elements. The unit cell structure of the resistive sheet is a meander line loaded with four lumped resistors, which generate a wide absorption band from 2.4 to 6.2 GHz, while the layer of FSS is coupled resonator spatial filter (CRSF) that generates a wide transmission band from 7.5 to 10.2 GHz. Furthermore, there is a 10.5 mm air spacer between the resistive and FSS layers. The period of the FSR structure, which maintains its passband and absorption band performance, is only 10 mm (0.08λ L). Simulated and measured results are compared and found to show good agreement.

This paper reports a dual-polarized graphene-based multi-functional device which could switch between rasorber and absorber flexibly. The only difference between rasorber and absorber is that rasorber has a transmission window with low loss. Therefore, a wideband absorber is proposed at the first step. Then, four split-ring resonators (SRRs) are introduced to the absorber, which makes the electromagnetic (EM) energy could be reflected at the certain frequency band. The state (on/off) of SRRs and absorber can be controlled by the chemical potential of graphene. To find a new pathway for this part of the reflected energy, metal ground of the absorber is replaced by a reconfigurable graphene-based FSS. The proposed FSS could be switched between FSS and metal plate by controlling the chemical potential of graphene ring embedded in the bottom metal layer. Therefore, the proposed multi-functional device could be obtained by combing the absorber with SRRs and reconfigurable FSS. When the proposed device serves as a rasorber, it has an absorption-transmission-absorption response with superior selectivity. When it performs as an absorber, it has wideband performance with high absorptive rate. It is an attractive candidate for stealth applications.

“…ese FSRs are usually composed of a lossy layer and a metallic lossless bandpass FSS layer. e lossy layer can be implemented by two methods: magnetic loss material [8] and metallic element loaded with lumped resistors [5][6][7][9][10][11][12][13][14][15][16]. us, the transmission band can be realized by the resonance of the lossy layer and the lossless layer, while the lossy layer is used to achieve absorption characteristics.…”

“…Originally, the absorption band and the transmission band are separated, which results in only one-side absorption (the absorption band below the passband [5][6][7] and the absorption band above the passband [8][9][10]). To achieve a transmission window in the absorption band, some methods have been reported [11][12][13][14][15][16][17].…”

A novel low-profile dual-polarization frequency-selective rasorber (FSR) with a transmissive window in the absorption band is proposed in this paper. Based on the equivalent circuit model (ECM), the principles of the impedance design are theoretically derived. Then, a two-layer structure model is constructed. The top layer is composed of a lossy three-legged loaded element (TLLE), and the bottom layer is composed of a square ring bandpass frequency-selective surface (FSS). Furthermore, the strips are folded to reduce the unit cell size to stabilize the angular response. The maximum stable response angle increases from 20 to 40° due to the miniaturized design under both TE and TM polarization. The experimental results of the prototype are in good agreement with the simulation results, which validates the rationality of our design.
