“…The major contributions of the screen‐printing method based absorptive‐FSS are as follows: Improving the performance with simple design method and efficient manufacturing process. In case of References , 1600 to 7200 lumped elements are required to implement the absorptive‐FSS with 20 × 20 arrangement. As the increase the number of lumped elements, not only the ohmic losses are higher, but also the soldering defects. Design error can be reduced by minimizing the resistance parasitics of chip resistor (inductance, capacitance). Practical design method for composition with fiber‐reinforced polymer composite material in the fabrication of a radome. Dimensions of chip resistor affect to forming the non‐uniform adhesive layer, which can be a critical problem, not only degrade performance of the radome but also structural stability. …”

“…In addition, the use of resistive sheet‐based FSS is limited as this kind of FSS is challenging to manufacture; for example, difficulty in implementation of the FSS with respect to optimal surface resistance properties is often encountered . To improve the limitations in the design method of these previous studies, other studies have proposed the use of FSS‐based resistive layers, which are composed of strip‐type L and C resonators or lumped elements such as resistors, inductors, and capacitors . However, a large number of components is required to implement stable properties for dual‐polarization, or there are difficulties with preventing reduced performance owing to uncertainties (tolerance, parasitic effects) in the electrical performance of lumped elements in high‐frequency bands as well as error factors (soldering) that can occur during the fabrication process.…”

This study uses screen-printing technology to create resistive components by employing carbon-based electric ink (55 Ω/□) printing, and an absorptive frequency selective surface (FSS) was designed with absorptive properties in the C-band and transmissive properties in the X-band. This was done to ensure structural stability and to overcome the limitations of lumped-element-based absorptive-FSS, which make it difficult to ensure the stability of electrical properties owing to thermal and mechanical factors in the hybrid composite laminated structure. The proposed structure reduces parasitic components by substituting printed resistive components instead of the lumped element having the weakness of a difficult to predict electrical performance according to the frequency band. Fabrication and measurement tests were performed to verify the performance of the proposed structure by comparing the frequency response properties in normal and oblique incidence conditions, the measured results show good agreement with the simulation results.

“…In other directions, it still has a strong out-of-band reflection, which results in an increased RCS. Hence, the traditional FSSs may be detected by bistatic or multi-static radars [12]. Therefore, a new ideal radome was proposed to compensate this deficiency, which is nearly transparent at the passband while the wave can be absorbed by the structure out of the passband.…”

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.

“…The lossy layer should be transparent at the notch band and meets the absorption condition beside the notch band. According to References and , the equivalent impedance of the lossy layer should be infinite (ie, impedance pole) to obtain a transmission closely to 100% whether the PIN diode sets to ON or OFF, and meet the general absorption condition (GAC) to achieve wide absorption band beside the notch band. In short, the key to realize switchable BNFSA lies on the design of the lossy layer.…”

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.
