“…An ideal FSR should have zero insertion loss (IL) for operating in-band electromagnetic (EM) signals while having 100% absorptivity for out-of-band signals [11][12][13][14]. To achieve these goals, both 2D-FSR and 3D-FSR have been developed in previously published studies [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. The 2D-FSR maintains the multilayer structural form similar to FSS, and it usually consists of a lossy resistive sheet and a lossless FSS layer [14,15].…”

“…Currently, according to the relative locations between the passband and the absorption band, FSRs can be divided into three basic types: absorption band above the passband; absorption band below the passband; and absorption (pass)band inside pass (absorption) band [25,26]. Different types of FSRs should meet individual requirements under different application scenarios.…”

A novel dual-polarized transmissive/absorptive frequency-selective rasorber (FSR) with an ultrawide absorption spectrum covering both the X- and Ku-bands is proposed in this paper. The FSR is constructed from a bottom lossless transmission layer and a top lossy absorption layer, in which a resistor-loaded incurved square loop strip line structure is utilized to obtain an ultrawide absorption band. To quantitatively analyze its operation principle, an accurate equivalent circuit model of the proposed FSR was developed. A 2D prototype was designed, assembled, fabricated, and measured. The FSR exhibits an absorption band that ranges from 8.1 to 19.1 GHz (81%) under normal incidence, whereas the passband insertion loss at 4.5 GHz is less than 0.45 dB. The total thickness of the FSR is only 5.1 mm, which keeps low profile characteristics. The simulation agrees well with the measured results.

“…Thus, FSRs with the pass band below or within the absorption band were realized [13]- [20]. Various parallel resonant structures have been proposed for this purpose, such as the circular spiral resonators [18], the centrosymmetric bended-strip resonator [20], and the square meander-line metallic loop [21].…”

A Frequency Selective Rasorber With Three Transmission Bands and Three Absorption Bands

et al. 2019

A frequency selective rasorber (FSR) with three transmission bands and three absorption bands is proposed in this paper. The FSR is constructed via cascading a lossy resistive surface and a multiple bandstop frequency selective surface (FSS) separated by air spacer. The transmission characteristics are obtained by the impedance poles of the interdigital capacitor-meander inductor resonators in the resistive surface and also the rectangular loop resonators in the FSS. The absorption bands are achieved using the ohmic loss of the resistors in the resistive surface along with the reflections of the FSS. The physical principle of operation of the multiband FSR is explained based on an equivalent circuit model. A prototype is fabricated and measured. The experimental results exhibit three transmission bands at 6.1 GHz, 8 GHz and 10 GHz with insertion loss below 0.9 dB, 0.8 dB and 0.8 dB, respectively. The effective absorption bands are in range of 7.05 GHz-7.55 GHz, 8.87-9.35 GHz and 12.59 GHz-14.22 GHz, respectively. The simulation results show the angular stability of the FSR response. In addition, the effect of FSR dimensions on the transmission/absorption bands is studied.

“…In the microwave band, researchers have proposed periodic structures that can absorb and transmit waves in different frequency bands, which are called frequency selective rasorbers (FSRs). FSRs with lower or higher absorption band have been proposed in [26,27,28,29]. However, FSRs can only absorb waves on one side of the passband, and only reflect waves on the other side, which is detrimental to antenna stealth.…”

In this paper, a dual-band terahertz absorber with two passbands is proposed. The absorber is composed of periodic patterned graphene arrays on the top of a SiO 2 substrate and a frequency selective surface (FSS) on the bottom of the substrate. The simulated results indicate that there are two absorption bands (absorption greater than 90%) ranging from 0.54 to 0.84 THz and 2.13 to 2.29 THz. It is almost transparent to incident waves (transmission greater than 50%) below 0.19 THz and between 1.3 and 1.67 THz with a center frequency of 1.49 THz. The absorber has a good tolerance to the transverse electric (TE) and transverse magnetic (TM) polarized wave oblique incidence, and the transmission rate of the passbands remains greater than 50% within 70 degrees. Moreover, the absorption rate of the absorber can be tuned by the chemical potential of graphene. The structure with absorption and transmission properties has potential applications in filtering, sensing, detecting and antenna stealth.
