Publication number: 20240076231Abstract: A proposed fabrication technique for a polarization-absorbing wire grid polarizer avoids the need to etch through the multilayer stack of materials to form the grid structure. Initial reflective metal and dielectric buffer layers are patterned and etched in a conventional manner to create the desired grid topology. A small-angle coating process is then used to complete the fabrication process by first coating the top surface of the patterned dielectric with a polarization-absorbing metal. A second coating process is used to cover the created metal coating with a dielectric cladding material. Maintaining a small angle of incidence between the coating source and the wire grid structure ensures that top portions of the grid are suitably covered to create the desired multilayer wire configuration.Type: ApplicationFiled: August 23, 2023Publication date: March 7, 2024Applicant: II-VI Delaware, Inc.Inventors: Junjie Yao, Jianying Zhang, Xiaolian Zhou, Xu Jia, Lei Lin, Guanglong Yu

Publication number: 20230107753Abstract: A method of atmospheric inorganic and organic nitrogen quantification is disclosed. The ambient air is sampled by drawing it through an inlet followed by a denuder to reduce positive artifacts. After artifact removal, the air sample is collected onto a filter. The filter is subjected to thermal evolution under stepwise temperature program to generate a gaseous product mixture. In the presence of oxygen-containing carrier gas, the gaseous product mixture is oxidized to form oxidized gaseous products of CO2 and nitrogen oxides. Then, the nitrogen oxides products are processed to form an NO product and reacted with ozone to form an excited NO2* molecule. By quantifying the intensity of fluorescence, the concentration of NO2* molecule is measured, which determines the nitrogen content in the aerosol sample. The differentiation of inorganic and organic nitrogen is achieved through processing the thermally evolved carbon and nitrogen signals using multivariate curve resolution data treatment.Type: ApplicationFiled: October 5, 2022Publication date: April 6, 2023Inventors: Jianzhen YU, Xu YU, Jinjian LI, Qianfeng LI, Xiaohui HUANG
