High-Performance Ultra-Broadband Absorber for Polarized Long-Wavelength Infrared Light Trapping

Ying Xiong, Xiaoyi Liu, Jian Zhang, Xiaokun Wang, Xiaoyi Wang, Jinsong Gao, Haigui Yang
2022 Coatings  
Conventional infrared polarization imaging and detection systems are normally complex, bulky, and expensive, since rare existing absorber components possess polarization selectivity, especially in the long-wavelength infrared (LWIR) range. In this study, we propose a novel high-performance metamaterial absorber with ultra-broadband high absorption and polarization selectivity in the entire LWIR atmospheric window. The absorber can realize an absorptance higher than 90% with a 4750 nm bandwidth

It exhibits precise polarization-selective absorption at the target wavelength; specifically, it can selectively trap TM-polarized light while restricting the absorption of TE-polarized light. In addition, the designed metamaterial exhibits remarkable spectral stability when the geometric parameters of the microstructure change, which is of great benefit in its manufacturing process. The proposed ultra-thin absorber provides a promising approach to simplify LWIR imaging and detection systems and further improve their performance.

Microcavity electrodynamics of hybrid surface plasmon polariton modes in high-quality multilayer trench gratings

In common plasmonic structures, absorption and radiation losses are often mutually restricted and can seriously influence the device performance. The current study presents a compound structure composed of multilayer grating stripes and multilayer shallow trenches. A small depth was adopted for the trench configuration to exclude the extra bend loss. These two sections supported Fabry-Perot resonance and cavity modes, respectively, with hybrid modes formed through intercoupling. In addition,

Significantly, such a low loss realized by the hybridization of surface plasmon polariton modes has rarely been seen before. Moreover, the debatable relationship between the total and partial quality factors was described for the first time based on a hybrid mode analysis to establish a new approach to investigate the different resonance modes. In the detailed calculation process, the relative electric field intensity was first adopted to stipulate the effective areas for the various modes, which is more reasonable than using the common definition that is based on a unit structure. The multilayer trench grating exhibited a relatively low loss without weakening energy localization, which is significant in the design of plasmonic devices.

and other issues challenging rangeland environments and societies have attracted strong attention from decision-makers, scholars and NGOs for decades. In addition, rangelands that have been marginalized from the development framework now have increased interactions and connections with external worlds through globalization, market connections and government intervention, coupled with climate change. There have been numerous empirical studies concerning these issues, but a more critical and

Restoring Community Connections to the Land: Building Resilience Through Community-based Rangeland Management in China and Mongolia edited by Maria E. Fernández-Giménez and her colleagues (five ecologists and sociologists from Colorado State University, USA, and Chinese Academy of Social Sciences, China) provides a framework of resilience thinking and seven detailed case studies of community-based rangeland management (CBRM) in China and Mongolia. These cases explore the potential for community-based natural resource management (CBNRM) for maintaining the resilience of rangeland social-ecological systems.

Spread-Spectrum Selective Camouflaging based on Time-Modulated Metasurface [article]

Xiaoyi Wang, Christophe Caloz
2019 arXiv   pre-print
This paper presents the concept of spread-spectrum selective camouflaging based on time-modulated metasurface. The spectrum spreading is realized by switching the metasurface between the reflective states of a PEC mirror and a PMC mirror, using an array of microstrip patches connected to the ground via diode switches, according to a periodic pseudo-random noise sequence. As the spectrum spreading induces a drastic reduction of the power spectral density of the signal, the level of the scattered

Moreover, the object can be detected by a friend radar possessing the spread-spectrum demodulation key corresponding to the metasurface modulation, and this detection is robust to interfering signals. The proposed system is analyzed theoretically, and demonstrated by both simulation and experimental results.

Argus: Interactive a priori Power Analysis [article]

Xiaoyi Wang, Alexander Eiselmayer, Wendy E. Mackay, Kasper Hornbæk, Chat Wacharamanotham
2020 arXiv   pre-print
A key challenge HCI researchers face when designing a controlled experiment is choosing the appropriate number of participants, or sample size. A prior power analysis examines the relationships among multiple parameters, including the complexity associated with human participants, e.g., order and fatigue effects, to calculate the statistical power of a given experiment design. We created Argus, a tool that supports interactive exploration of statistical power: Researchers specify experiment

Argus then simulates data and visualizes statistical power across these scenarios, which lets researchers interactively weigh various trade-offs and make informed decisions about sample size. We describe the design and implementation of Argus, a usage scenario designing a visualization experiment, and a think-aloud study.

Eye-Tracking Technology in Online Real Estate Rental

Jie Sun, Zhiruo Wang, Xiaoyi Dang, Yang Zhang, Pengwei Wang
2021 Scientific Programming  
In China in recent years, the rental housing market has boomed, but insufficient attention has been paid to microsubject tenants in the market, and there is a lack of research results on tenants' decision-making processes. In keeping with the characteristics of China's accommodation-renting population, this study takes as its research object graduating students, who form an important group in the housing rental market, and focuses on the information retrieval process underlying prospective

Second, using eye-tracking experiments, the real online renting process is simulated and tenants' web listings are analyzed qualitatively and quantitatively. In the process of information search, the characteristics and rules of browsing the entry search page, the listings page, and the details page are obtained, and the factors that prospective tenants pay attention to in their search for rental information are obtained. The research results show that initial alphabetical sorting of the term search page can improve the subjects' efficiency in locating the target keywords, the text information display area of the listings page receives more attention than others, and the real concern factors of the tenants on the page listing details are generally consistent with their selected factors but deviate slightly. Finally, the layout and display of web page information affect how subjects' attention is distributed, and web page information presents a significant difference in attention between upper and lower pages.
