A Paper-based Lightweight Absorber with Ultra-wide Absorption Band

2021 IEEE Asia-Pacific Microwave Conference (APMC) (2020)

Xin Xiu Wenquan Che Shaowei Liao Quan Xue Haidong Chen

This work presents a novel lightweight absorber with ultra-wide absorption band. The proposed absorber is designed on one kind of periodic rectangle cellular structure made of aramid paper, which is placed above one thin metal film. Each cellular cell contains one rectangle cavity filled with air, while taper shaped resistive patterns are printed on the walls of the cavity to produce energy losses. Under the normal incidence, the simulated results show that the bandwidth for the absorber with reflection less than -10 dB has a wide absorption band (reflection <; -10dB) from 4.87 GHz to 30GHz, and the thickness of the absorber is only 10mm.

Transparent FSS on Glass Window for Signal Selection of 5G Millimeter-Wave Communication

IEEE Antennas and Wireless Propagation Letters (2021)

Hao Chen Haidong Chen Xin Xiu Quan Xue Wenquan Che

A transparent frequency selective surface (FSS) on a glass window is proposed for signal selectivity of 5G millimeter-wave communication, based on a transparent and low loss material cyclic olefin copolymer (COC). The proposed FSS based on dual-loop units is designed on both sides of COC, which helps to realize the band-pass filtering effect under both normal and oblique-incident conditions in the desired frequency range from 27.5 to 29.5 GHz. The metal-meshed technology is employed to enhance the light transmission of the circuits, and the measured performances with traditional glass show that our proposed concepts can be a potential solution for signal filtering at millimeter wave on glass windows.

Design of a Three-dimensional Bandpass Frequency Selective Surface Based on Coupled-slotlines

2021 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP) (2022)

Songyu Feng Ye Han Xin Xiu Wenquan Che Quan Xue

In this paper, a 3-D planar bandpass frequency selective surface (FSS) element is presented. Each FSS element consists of coupled-slotlines and slotlines on a printed circuit board (PCB), and then the equivalent transmission model is established and analyzed by comparing with full-wave simulation results. To obtain the desirable bandwidth of the upper stopband, a stepped-impedance resonator (SIR) is introduced between the two coupled-slotlines to suppress the first harmonic in the upper stopband Finally, the design is further extended to a dual-polarized structure with a miniaturized structure. The resultant dual-polarized FSS exhibits a bandpass response at around 5 GHz with harmonic suppression, the stability of polarization under oblique incidence.

Double-Polarized Dual-Passband Absorptive Frequency-Selective Transmission Structure

IEEE Transactions on Electromagnetic Compatibility (2019)

Xin Xiu Wenquan Che Wanchen Yang Ye Han Quan Xue

Double-polarized dual-band absorptive frequency-selective transmission structure (AFST) is presented, which has two passbands within a wide absorption band. Equivalent circuit models (ECMs) are presented to assist the structure design efficiently. Based on the verified ECMs, practical AFSTs are then constructed accordingly. One single-band AFST is first designed, which is realized by introducing slot and cross-frame slot (CFS) resonators in the lossy and lossless layers of one broadband absorber, respectively. As a result, one passband is achieved, while the absorption at both sides is maintained. Furthermore, by using multiple slots and CFS resonators with different resonant frequencies, two transmission poles are, respectively, achieved at 3.5 GHz and 4.9 GHz, and the dual-bandpass performance is achieved. Under normal incidence, the operating frequency bands (reflection <; -10 dB) of the proposed AFSTs are larger than 110%, while the minimum insertion losses are less than 0.25 dB. For demonstration, one prototype of the dual-band AFST is fabricated and measured, and a reasonable agreement between the simulated and measured results is observed.

Review and Modification of Permittivity Measurement on Open Resonator for Transparent Material Measurements at Terahertz

IEEE Transactions on Instrumentation and Measurement (2020)

Haidong Chen Hao Chen Wenquan Che Shimin Zheng Xin Xiu

In this article, permittivity measurement based on open resonator technology is reviewed, and then, the hemispherical open resonator with an enlarged aperture on the curved mirror is proposed for high-frequency applications. A numerical compensate method based on frequency deviation is first proposed in detail for permittivity correction. To verify our idea, an open resonator is designed and fabricated over the frequency from 26 to 40 GHz, and some materials with known characteristics are measured based on proposed technology. The complex permittivity measurement of two transparent materials, polydimethylsiloxane (PDMS) and cyclic olefin copolymer (COC), are studied at 260 GHz. Measured results are compared with previous ones, and the discussion is provided, which shows that the proposed method probably is an efficient way for complex permittivity measurement at high frequency up to terahertz.
