Large-area ultracompact pixelated aluminumwire-grid-based metamaterials for Vis-NIR full-Stokes polarization imaging

引用

Photonics Research 2023年第11期11卷 1975-1986页

作者： YUANYI FAN JINKUI CHU RAN ZHANG CHUANLONG GUAN jianying liu State Key Laboratory of High-performance Precision Manufacturing Dalian University of TechnologyDalian 116024China Key Laboratory for Micro/Nano Technology and System of Liaoning Province Dalian University of TechnologyDalian 116024China

The study of pixelated metamaterials that integrate both the functions of linear and circular polarization filters is rapidly growing due to the need for full-Stokes polarization imaging. However, there is a lack of large-area, ultracompact pixelated full-Stokes metamaterials with excellent performance, especially circular polarization filters with a high extinction ratio, a broad operating bandwidth, and a low-cost, high-quality, efficient manufacturing process, which limits the practical applications of pixelated full-Stokes metamaterials. In this study, we propose a universal design and fabrication scheme for large-area, ultracompact pixelated aluminum wire-grid-based metamaterials used in Vis-NIR full-Stokes polarization imaging. The aluminum wire-grid was designed as a linear polarization filter with an average linear polarization extinction ratio of 36,000 and a circular polarization filter with an average circular polarization extinction ratio of 110 in Vis-NIR. A large-area, ultracompact 320 × 320pixelated aluminum wire-grid-based full-Stokes metamaterial was fabricated using nanoimprint lithography and nano transfer printing with the advantages of low cost and high efficiency. This metamaterial was used to achieve full-Stokes polarization imaging with errors within 8.77%, 12.58%, 14.04%, and 25.96% for Stokes parameters S_(0), S_(1), S_(2), and S_(3), respectively. The inversion errors of the compensated Stokes parameters can be reduced to0.21%, 0.21%, 0.42%, and 1.96%, respectively.

Discussion on origin of clay minerals in outcropped sandstone from Lower Cretaceous Chengzihe Formation and Muling Formation in Jixi Basin

引用

Global Geology 2009年第1期12卷 1-4页

作者： liu jianying liu Li QU Xiyu Exploration ＆ Development Research Institute of Daqing Oilfield Company Ltd. Daqing 163712 Heilongjiang China College of Earth Sciences Jilin University Changchun 130061 China

Clay minerals in the outcropped sandstone from Lower Cretaceous Chengzihe Formation and Muling Formation in Jixi Basin were analyzed by X-ray diffraction. The results show that the clay minerals mainly consist of illite, kaollinite and illite/smectite, which can be divided into two types： kaolinite- and illite/smectite types. The outcropped sandstone occurred in middle diagenetic stage-A on the basis of the clay mineral composition. The development factor of the formation of kaolinite type clay mineral is caused mainly by the organic acid from the coal-bearing formation and nmdstone during the diagenesis process in Lower Cretaceous Chengzihe Formation and Muling Formation in the Jixi Basin. The weak hydrodynamic force of sedimentary facies made the sandstone leaching condition poor, which is the reason forming the aggregation of clay minerals of the illite/ smectite-and illite types.

Diagenesis of Paleogene sandstone from Kong 1 Member of Southern Kongdian in Huanghua depression

引用

Global Geology 2007年第1期10卷 39-43页

作者： Jinping MA Linfu XUE Ling DING jianying liu Danping WANG College of Earth Sciences Jilin University Changchun 130026 China

Huanghua depression is one of the richest areas in petroleum and natural gas in China. The Paleogene mainly consists of sandstone with facies of river, delta, fan delta and littoral-shallow lacustrine. Diagenesis played an important role in the properties of reservoir rocks. Applying X-ray diffraction, on the basis of analyz- ing many cores and thin sections, the authors studied diagenesis of Paleogene sandstone reservoir rocks in kongl Menber of southern Kongdian in Huanghua depression. Diagenetic complexity shows that the sandstone in this area underwent compaction, cementation, isolation, recrystallization during the burying of sediments, and the first three compose the major diagenesis. The compaction and cementation led to decreasing porosity, and the solution of unsteady minerals also results in increasing in porosity.

Diffusion tensor imaging detects Wallerian degeneration of the corticospinal tract early after cerebral infarction

引用

Neural Regeneration Research 2012年第12期7卷 900-905页

作者： Ruiman Xie Min Fang Linjiang Zhou Shanghua Fan jianying liu Hongbo Quan Man Luo Dongying Qiu Department of Neurology and Gerontology Zhongshan Hospital Fudan University Shanghai 200032 China Department of Radiology Huashan Hospital Fudan University Shanghai 200040 China

To investigate the feasibility and time window of early detection of Wallerian degeneration in the corticospinal tract after middle cerebral artery infarction, 23 patients were assessed using magnetic resonance diffusion tensor imaging at 3.0T within 14 days after the infarction. The fractional anisotropy values of the affected corticospinal tract began to decrease at 3 days after onset and decreased in all cases at 7 days. The diffusion coefficient remained unchanged. Experimental findings indicate that diffusion tensor imaging can detect the changes associated with Wallerian degeneration of the corticospinal tract as early as 3 days after cerebral infarction.
