“…Compact lumped-element superconducting resonators were developed earlier for use as backward-wave microwave filters [47][48][49]. Superconducting multi-mode composite SRRs have been used as microwave filters and show very low insertion loss and excellent out-of-band rejection [50,51]. More recently a novel compact fractal superconducting resonator has been developed utilizing only narrow superconducting lines, making it less susceptible to external magnetic fields [52].…”

We review progress in the development and applications of superconducting metamaterials. The review is organized in terms of several distinct advantages and unique properties brought to the metamaterials field by superconductivity. These include the lowloss nature of the meta-atoms, their compact structure, their extraordinary degree of nonlinearity and tunability, magnetic flux quantization and the Josephson effect, quantum effects in which photons interact with quantized energy levels in the meta-atom, as well as strong diamagnetism.

In this paper, we proposed an optimized structure, named direct‐connected T‐shaped stub‐loaded resonator (DC‐TSSLR), which generates nine high‐performance resonant modes (RMs) while the conventional works only produces two RMs (odd‐ and even‐mode) with the similar structure. Based on this method, a triple‐band nine‐RM bandpass filter (BPF) is realized with fractional bandwidths (FBW) of 65%, 42%, and 31%, the insertion losses (IL) of 0.11 dB, 0.21 dB, and 0.37 dB and the return losses (RL) of 42.9 dB, 44.5 dB, and 42.9 dB, respectively. In addition, this scheme was further developed into a modularized design for multi‐mode filter design. As example, by cascading another DC‐TSSLR, a dual‐wideband BPF with eight RMs is realized with the FBW of 55% and 38%, the IL of 0.15 dB and 0.4 dB and the RLs of 16.2 dB and 21.7 dB, respectively. The proposed method offers a modularized‐design scheme for multiband BPF design as well as the reference for RMs modulation.

In this paper, a dual-wideband bandpass filter (BPF) with independently controllable center frequencies (CFs) and wide stopband suppression is presented using a new quintuple-mode resonator (QMR). By applying the classical odd-/even-mode analysis method, the resonant characteristics of the new QMR have been analyzed. It shows that five modes can be excited, and two of them can be employed to form the lower passband, while the other three modes contribute to the higher passband. For verification, a dual-wideband BPF using the new QMR is designed, fabricated, and tested. Experimental results show that the CFs of the dual-wideband BPF centered at 2.96 GHz and 5.695 GHz with 3 dB fractional bandwidths of 27.7 and 23.4%, respectively. In addition, 20-dB suppression in upper-stopband ranges from 2.23 to 4.04f0, where f0 is the center frequency of the first passband. The measurement results are in good agreement with the prediction results.
