“…7 To improve the functional diversity, absorptive structures with hybrid resonators have been published to realize the transmission window above the absorption band. [8][9][10] Within the passband of these designs, out-of-phase currents can be generated on the lossless element, and the electric dipole moment can be canceled. The works mentioned above are achieved by employing the resonant transmission window.…”

A dual‐polarized frequency‐selective absorptive structure with a wide transmission band is presented in this article. The passband is achieved by employing the modal interaction pole of the lossy array, and the multiresonant operating modes are discussed. By combining with the lossless square array, the desired transmission and absorption behaviors are obtained. Due to the modal interaction pole, the current on the lossy layer is effectively reduced, and a wide passband with high transmittance is generated. The −3 dB fractional pass bandwidth is 47.8% with a minimum insertion loss of 0.17 dB. Furthermore, a wide absorption band is achieved by employing the three resonances of the lossy array, and the absorptivity is above 99% from 5.5 to 6.5 GHz. Only four resistors are loaded on the edges of the lossy array to provide the absorption performance at the stopband. Finally, a good agreement between the simulation and measurement results validates the presented design.

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.

“…The insertion loss (IL) of pass-band and the fractional bandwidth (FBW) of the 10-dB-absorption band (with the reflec-tion coefficient less than −10 dB) are two criteria for evaluating FSR. In recent years, various FSRs have been widely investigated, such as the FSRs with high-frequency passband proposed in [13,14,15,16], and the FSRs with twosided absorption bands reported in [17,18,19,20,21,22,23,24,25,26]. Besides, to meet the stealth requirements of low-frequency antenna systems, several FSRs with lowfrequency pass-band were also presented in [27,28,29,30,31].…”

A low-frequency transmissive frequency selective rasorber (FSR) with high in-band transmission and wideband absorption characteristics is proposed and experimentally demonstrated. It comprises the top resistive sheet and the bottom bandpass FSS. For resistive sheet, the tiny strip-type parallel LC resonator composed of square spiral inductor and its two-sided capacitors is inserted between the resistor-loaded crosses to achieve lower insertion loss (IL) by cutting off the lossy path. The bandpass FSS with high selectivity consists of Jerusalem cross slot array and capacitive metallic patches. An IL of 0.3 dB is obtained at 3.55 GHz, and the 10-dB-absorption band is 5.4-13.2 GHz.
