“…Indeed, some passive devices based on TSV have been proposed [3,11]. Recently, due to the large-scale expansion of semiconductor technology and emerging markets such as automotive radar and 5G, TSV technology has been gradually extended to MMW and THz fields [12][13][14]. In 2022, a silicon substrate integrated gap waveguide (SSIGW) utilizing TSV was proposed to address the aforementioned issues, and it has been successfully applied in the design of a 6G filtering metalens antenna [15].…”

A meta-surface-based arbitrary bandwidth filter realization method for terahertz (THz) future communications is presented. The approach involves integrating a meta-surface-based bandstop filter into an ultra-wideband (UWB) bandpass filter and adjusting the operating frequency range of the meta-surface bandstop filter to realize the design of arbitrary bandwidth filters. It effectively addresses the complexity of designing traditional arbitrary bandwidth filters and the challenges in achieving impedance matching. To underscore its practicality, the paper employs silicon substrate integrated gap waveguide (SSIGW) and this method to craft a THz filter. To begin, design equations for electromagnetic band gap (EBG) structures were developed in accordance with the requirements of through-silicon via (TSV) and applied to the design of the SSIGW. Subsequently, this article employs equivalent transmission line models and equivalent circuits to conduct theoretical analyses for both the UWB passband and the meta-surface stopband portions. The proposed THz filter boasts a center frequency of 0.151 THz, a relative bandwidth of 6.9%, insertion loss below 0.68 dB, and stopbands exceeding 20 GHz in both upper and lower ranges. The in-band group delay is 0.119 ± 0.048 ns. Compared to reported THz filters, the SSIGW filter boasts advantages such as low loss and minimal delay, making it even more suitable for future wireless communication.

“…On the other hand, there is also much literature based on advanced high-precision semiconductor technologies, such as deep reactive ion etching (DRIE) [9,10], silicon via (TSV) [11,12], and microelectromechanical systems (MEMS) [13][14][15][16][17], to achieve the manufacturing of terahertz filters. Ideally, with the improvement of fabrication accuracy, performance errors can be reduced to a lower level, but due to the maturity of advanced semiconductor technology and material limitations, the current performance of terahertz devices is not excellent.…”

The directional optimization correction (DOC) method is proposed to reduce the performance error between desired and fabricated terahertz (THz) devices. Three 340 GHz terahertz filters with a bandwidth of 20 GHz are designed and fabricated. The traditional global optimization correction (GOC) method and the proposed DOC method are used to optimize and reduce the performance error, respectively. It is garnered that the center frequency error and bandwidth error of the fabricated terahertz filter optimized by the GOC method are reduced to 3.5 GHz (~1.03%) and 2.2 GHz (~11%), respectively. Meanwhile, the center frequency error and bandwidth error of the fabricated terahertz filter optimized by the DOC method are reduced to 0.2 GHz (~0.06%) and 0.4 GHz (~2.0%), respectively, which has fewer optimization parameters and higher accuracy than the GOC method. Furthermore, the in-band return loss (RL) of two optimized terahertz filters based on the DOC and GOC methods is less than 15 dB, and the in-band insertion loss (IL) is less than 2.3 dB.
