“…In order to verify the correctness of our proposed structure, the equivalent circuit model (ECM) is used to preanalyze the structure. 12,15 PIN diode is in the ON state, it can be represented by an inductance L on and a small resistance R on in series, which are 0.4 nH and 1.5 Ω respectively. In the OFF state, the PIN diodes can also be modeled as the parallel connection of a capacitor C off and a large resistor R off , with the values of 0.08 pF and 5 kΩ, respectively.…”

In this article, a transmission and reflection states switchable Luneburg lens (LL) reflector based on active frequency selective surface (AFSS), namely LL-AFSS reflector, is proposed. The reflector is composed of a miniaturized AFSS reflector, which can change the working state, and a LL composed of six layers and five media from inside to outside. By changing the bias voltage of the PIN diode loaded on the AFSS reflector, the transmission and reflection working states of the LL reflector can be freely switched in the frequency range of 3.5-5 GHz. When the PIN diodes are in ON state, the incident electromagnetic wave will not be reflected through the LL reflector. When the PIN diodes are in OFF state, the radar cross section (RCS) generated by the LL reflector to the incident electromagnetic wave reaches about 15 dB within the angle range of À30 ≤ φ ≤ 30 . The electromagnetic numerical simulation and experimental sample verification of LL-AFSS reflector are carried out. The results show that the proposed design method is feasible and the RCS changes of transmission and reflection characteristics of LL reflector are obvious.

“…The simulation results indicated that the absorptivity of the proposed absorber remained above 90% within the frequency range of 16.52-100.00 GHz. In addition, water has the unique advantage of liquidity in the design of reconfigurable metamaterial systems [25,26,[32][33][34][35][36]. In [32], a water-based reconfigurable FSR has been proposed for the first time, which consists of a 3D printed container and a bandpass FSS.…”

In this paper, a multifunctional frequency selective rasorber (FSR) based on hybrid microfluidic-electronic control is presented. The proposed FSR consists of a photosensitive resin-based microfluidic channel and an active frequency selective surface (AFSS). The lossy layer utilizes the special properties of water (dispersion characteristics, fluidity), and has great advantages in low profile, multi-function and low costs. Four different responses are realized by the combination of two independent control systems, which provides more degrees of freedom for manipulating electromagnetic waves. In addition, the distribution of electric fields and power loss densities are thoroughly analyzed to derive the physical properties of the proposed structure. Finally, a multifunctional FSR is fabricated and measured, and the simulated and tested results are in good agreement. The proposed structure performs under different polarizations and incident angles (up to 30°), which ensures the stability and security of the communication system in complex environments.

In this letter, a new triple‐band millimeter‐wave frequency selective surface (FSS) is presented. The proposed FSS structure consists of three slot‐based resonance mechanisms on the single layer of Rogers Diclad880 dielectric. It shows a high compactness with a unit cell surface area of 5.4 × 5.4 mm2. The proposed FSS exhibits a triple‐band bandpass filter characteristics for the allocated 5G millimeter‐wave frequency regions with sufficient bandwidths corresponding to 23.5–24.6, 27–28.5, and 37.5–41 GHz, respectively. Simulation outcomes reveal that the FSS poses polarization insensitive behavior, and maintains high transmission skill for a wide range of incident angles up to 40°. A 40 × 40 FSS panel is fabricated, and the experimental verification is carried out. The outcomes prove that the proposed FSS is suitable for multiband 5G millimeter‐wave filtering applications.
