11Plasmonic Bloch Oscillations and Resonant Zener Tunneling in Subwavelength Metal-Dielectric-Air Waveguide Superlattices显示文摘In this paper,we study the propagation properties of surface plasmon polaritons in plasmonic single-cavity superlattices and two-cavity superlattices which are composed of two kinds of alternately stacked subwavelength metal-dielectric-air waveguides with large dispersion.Theoretical predictions of plasmonic time-resolved Bloch oscillations existing in single-cavity superlat-tices and resonant Zener tunneling(ZT) occurring in two-cavity superlattices by the transfer matrix method(TMM) are well dem-onstrated by the numerical simulations on the propagation of SPPs pulse in the two kinds of superlattices by the finite-difference time-domain(FDTD) method.The two proposed superlattices can be conveniently fabricated by present nanotechnology,and the study may promote the realization of plasmonic BO and resonant ZT in nanoscale devices experimentally.LIN Weihua LI Qiuze YAO Jin ZHU Daiwei ZHANG Shuo 2012Wuhan University Journal of Natural Sciences2012,17,2:0
12Experimental study of the wheel/rail impact caused by wheel flat within 400 km/h using full-scale roller rig显示文摘Purpose–In service,the periodic clashes of wheel flat against the rail result in large wheel/rail impact force and high-frequency vibration,leading to severe damage on the wheelset,rail and track structure.This study aims to analyze characteristics and dynamic impact law of wheel and rail caused by wheel flat of high-speed trains.Design/methodology/approach–A full-scale high-speed wheel/rail interface test rig was used for the test of the dynamic impact of wheel/rail caused by wheel flat of high-speed train.With wheel flats of different lengths,widths and depths manually set around the rolling circle of the wheel tread,and wheel/rail dynamic impact tests to the flats in the speed range of 0–400 km/h on the rig were conducted.Findings–As the speed goes up,the flat induced the maximum of the wheel/rail dynamic impact force increases rapidly before it reaches its limit at the speed of around 35 km/h.It then goes down gradually as the speed continues to grow.The impact of flat wheel on rail leads to 100–500 Hz middle-frequency vibration,and around 2,000 Hz and 6,000 Hz high-frequency vibration.In case of any wheel flat found during operation,the train speed shall be controlled according to the status of the flat and avoid the running speed of 20 km/h–80 km/h as much as possible.Originality/value–The research can provide a new method to obtain the dynamic impact of wheel/rail caused by wheel flat by a full-scale high-speed wheel/rail interface test rig.The relations among the flat size,the running speed and the dynamic impact are hopefully of reference to the building of speed limits for HSR wheel flat of different degrees.Chongyi Chang Yuanwu Cai Bo Chen Qiuze Li Pengfei Lin 2022Railway Sciences2022,1,1:0
