| 1 | TRANSPORT OF THE SUSPENDED SEDIMENT IN THE CHANGJIANG ESTUARY显示文摘The Changjiang River is characterized by the enormous volume of runoff and the great amount of sediment load with remarkable seasonal variation. The annual runoff sometimes is respondent to the amount of sediment load, and sometimes not. The amount of monthly sediment load after the month of the maximum runoff is larger than those before the month. The sediment concentration and net quantity of sediment transport in the vicinity of the river mouth varies greatly in time between the ebb and flood, spring and neap, and dry seasons and flood seasons. The three bifurcations also have differences in concentration and net quantity in space. Even in the same bifurcation they have differences in and out of the sand bar. At present, the North Channel is the main passage for water and sediment load emptying into the sea from the Changjiang River. More than 50 percent of the sediments from the river basin are deposited nearby the South Branch entrance and the main depositional area is situated in subaqueous delta off the South Channel. Between 122°30’E and 123°E is an important boundary for eastward sediment dispersion from which the suspended sediment are dispersed towards the east by south. | SHEN Huanting Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China LI Jiufa Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China ZHU Huifang Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China HAN Mingbao Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China ZHOU Fugen Department of Marine Geology, Tongji Univcrsity, Shanghai, China | 1992 | International Journal of Sediment Research1992，7，3： | 37 |

| 3 | Leaky cavity modes in metasurfaces:a route to low-loss wideband anomalous dispersion显示文摘Metasurfaces have provided unprecedented degrees of freedom in manipulating electromagnetic waves upon interfaces.In this work,we first explore the condition of wide operating bandwidth in the view of reflective scheme,which indicates the necessity of anomalous dispersion.To this end,the leaky cavity modes(LCMs)in the metaatom are analyzed and can make effective permittivity inversely proportional to frequency.Here we employ the longitudinal Fabry-Perot(F-P)resonances and transverse plasmonic resonances to improve the LCMs efficiency.It is shown that the order of F-P resonance can be customized by the plasmonic modes,that is,the F-P cavity propagation phase should match the phase delay of surface currents excited on the meta-atom.The nth order F-P resonance will multiply the permittivity by a factor of n,allowing larger phase accumulation with increasing frequencies and forming nonlinear phase distribution which can be applied in weak chromatic-aberration focusing design.As a proof-of-concept,we demonstrate a planar weak chromatic-aberration focusing reflector with a thickness ofλ_(0)∕9 at 16.0-21.0 GHz.This work paves a robust way to advanced functional materials with anomalous dispersion and can be extended to higher frequencies such as terahertz,infrared,and optical frequencies. | XIAOFENG WANG JIAFU WANG YAJUAN HAN MINGBAO YAN YONGFENG LI TONGHAO LIU HUA MA SHAOBO QU | 2023 | Photonics Research2023，11，6： | 0 |
