| 1 | Multiple resonant excitations of surface plasmons in a graphene stratified slab by Otto configuration and their independent tuning显示文摘Multiple resonant excitations of surface plasmons in a graphene stratified slab are realized by Otto configuration at terahertz frequencies. The proposed graphene stratified slab consists of alternating dielectric layers and graphene sheets, and is sandwiched between a prism and another semi-infinite medium. Optical response and field distribution are determined by the transfer matrix method with the surface current density boundary condition.Multiple resonant excitations appear on the angular reflection spectrum, and are analyzed theoretically via the phase-matching condition. Furthermore, the effects of the system parameters are investigated. Among them, the Fermi levels can tune the corresponding resonances independently. The proposed concept can be engineered for promising applications, including angular selective or multiplex filters, multiple channel sensors, and directional delivery of energy. | JIN YAO YING CHEN LONGFANG YE NA LIU GUOXIONG CAI QING HUO LIU | 2017 | Photonics Research2017，5，4： | 1 |
| 2 | A digital microfluidic single-cell manipulation systemoptimized by extending-depth-of-field device显示文摘Microfuidic systems have been widely utilized in high-throughput biology analysis,but thedificulties in iquid manipulation and cell cultivation limit its application.This work has developed a new digital microfluidic(DMF)system for on-demand droplet control.By adopting anextending-depth-of-field(EDoF)phase modulator to the optical system,the entire depth of themicrofluidic channel can be covered in one image without any refocusing process,ensuring that 95%of the particles in the droplet are captured within three shots together with shaking pro-cesses.With this system,suspension droplets are generated and droplets containing only oneyeast cll can be recognized,then each single cell is cultured in the array of the chip.Byobservingtheir growth in cell numbers and the green fluorescence protein(GFP)production via fluorescence imaging,the single cell with the highest production can be identified.The results haveproved the heterogeneity of yeast cells,and showed that the combined system can be applied forrapid single-cell sorting,cultivation,and analysis. | Qiushu Chen Qi Meng Yuzhe Liu Xiangan Long Yawei Kong Longfang Yao Liwen Chen Chuanyong Wu Kaiqin Chu Lan Mi Jiong Ma | 2023 | Journal of Innovative Optical Health Sciences2023，16，3： | 0 |
