“…Yu et al demonstrated a dual-band bandpass all-dielectric FSS, and introduced additional cylindrical DRs to broaden the bandwidth and to sharpen the cut-off frequency. 46 These works show that the bandpass or bandstop responses arise from impedance matching or mismatching, which is caused by the coupling manner of electric and magnetic resonances.…”

Frequency selective surface (FSS) has been extensively studied due to its potential applications in radomes, antenna reflectors, high-impedance surfaces and absorbers. Recently, a new principle of designing FSS has been proposed and mainly studied in two levels. In the level of materials, dielectric materials instead of metallic patterns are capable of achieving more functional performance in FSS design. Moreover, FSSs made of dielectric materials can be used in different extreme environments, depending on their electrical, thermal or mechanical properties. In the level of design principle, the theory of metamaterial can be used to design FSS in a convenient and concise way. In this review paper, we provide a brief summary about the recent progress in all-dielectric metamaterial frequency selective surface (ADM-FSS). The basic principle of designing ADM-FSS is summarized. As significant tools, Mie theory and dielectric resonator (DR) theory are given which illustrate clearly how they are used in the FSS design. Then, several design cases including dielectric particle-based ADM-FSS and dielectric network-based ADM-FSS are introduced and reviewed. After a discussion of these two types of ADM-FSSs, we reviewed the existing fabrication techniques that are used in building the experiment samples. Finally, issues and challenges regarding the rapid fabrication techniques and further development aspects are discussed.

“…Frequency selective surfaces (FSSs) can be considered as spatial microwave filters with three-dimensional frequency transfer functions made of periodic unit cells, which can be used in absorbers, 1 linear to circular polarization converters, 2 reflectors, 3 spatial filters, [4][5][6][7] shielding 8 and radomes. 9 The multi-band FSSs with independent transmission bands are required in many applications such as satellite communication systems.…”

In this paper, a dual polarized, dual band, low profile, embedded bias network, and compact tunable varactor band pass frequency selective surface (FSS) is designed with a wide tuning range. The proposed FSS is composed of two metallic layers printed on both sides of the substrate, where the top side has two cross strips with different dimensions encircled with high pass grids, whereas the bottom side includes a proper bias network. The loaded varactors between the grids and the cross strips with a designed bias network achieve two independent tunable pass bands. Moreover, an equivalent circuit of the FSS is extracted, which show good agreement with the full wave simulation results. The proposed FSS can operate from 2.28 GHz to 4.66 GHz and from 5.44 GHz to 11.3 GHz by proper tuning of the varactors loaded in the large and small cross strips. The tunable range of the low and high pass bands are about 70% with respect to the center frequency of each pass band. The electrical dimensions of the proposed FSS are about 0.05k Â 0.05k, where k is the free space wavelength at a lower pass band (2.28 GHz). Moreover, the proposed FSS works properly up to 60 incident angles. Published by AIP Publishing. https://doi.

“…A variety of BPFs based on metamaterials have been broadly studied, focusing on how to realize the ultrabroad bandwidth and high transmission rate. [8][9][10][11][12] Han et al reported a THz BPF by combining a metal-dielectric-metal (MDM) sandwich with a periodic slot structure. [13] Chiang et al experimentally demonstrated an ultrabroad THz BPF based on a composite metamaterial.…”

We report the design of a novel multiband metamaterial bandpass filter (BPF) in the terahertz (THz)-wave region. The designed BPF is composed of a metal-dielectric-metal sandwiched structure with three nested rings on the top surface and a cross structure on the bottom surface. Full-wave simulation results show that the designed BPF has three transmission peaks at frequencies of 0.42, 1.27, and 1.86 THz with transmission rates of −0.87, −1.85, and −1.83 dB, respectively. Multi-reflection interference theory is introduced to explain the transmission mechanism of the designed triple-band BPF. The theoretical transmission spectrum is in good agreement with the full-wave simulated results. The designed BPF can maintain a stable performance as the incident angle varies from 0 • to 30 • for both transverse electric and transverse magnetic polarizations of the incident wave. The designed BPF can be potentially used in THz devices due to its multiband transmissions, polarization insensitivity, and stable wide-angle response in the THz region.
