| 1 | Design and simulation of a compact ultra-wideband bandpass filter with a notched band using multiple-mode resonator technique显示文摘A novel, compact, and highly selective ultra-wideband(UWB) bandpass filter with a narrow notched band is presented. Apart from having a basic structure of a slotline multiple-mode resonator(MMR) and microstrip feed lines, this novel design introduces a cross-coupling between the input and output feed lines to enhance the filter selectivity. The design strictly follows the theory and verified by electromagnetic(EM) simulation and experiments. In addition, the narrow notched band is introduced by embedding a pair of split ring resonators(SRR) in order to reject any undesired existing radio signals that may interfere with the Federal Communications Commission(FCC)-defined UWB band. By changing the structural parameters of SRR, it can be easily tuned to any desired frequency. This filter can be integrated in UWB communication systems and efficiently improve the interference immunity from undesired signals such as wireless local area network(WLAN). | Yang Hong Chen Jing Yang Haolan Liu Yunlong Yang Yuchuan | 2016 | The Journal of China Universities of Posts and Telecommunications2016，23，1： | 6 |
| 2 | Understanding electrokinetic thermodynamics in nanochannels显示文摘Understanding the electrokinetic conversion efficiency in a nanochannel is vital for designing energy storage and conversion devices.In this paper,an analytical electrokinetic energy conversion efficiency in a nanochannel is obtained based on the linear electrokinetic response.The analytical result shows that the conversion efficiency has a maximum with the increasing of the nanochannel pore radius.Numerical solutions based on the Poisson-Nernst-Planck(PNP)and Navier-Stokes(NS)equations are used to confirm the analytical expressions.Besides,the influences of the pore radius and surface roughness on the conversion efficiency in nanochannels are also studied by the numerical calculations.In particular,the influences of the surface roughness on the fluid flow,streaming current and streaming potential are examined.The results show that the large bumps and grooves representing the roughness can hinder the fluid flows and ion transports in the nanochannels.The maximum efficiency in a smooth nanochannel is higher than that in a rough channel.However,the small bumps and grooves can increase the surface area of the channel,which is beneficial to improving the conversion efficiency in some cases.This research can provide theoretical guidance to design electrokinetic energy conversion devices. | Jianglong Du Haolan Tao Jie Yang Cheng Lian Sen Lin Honglai Liu | 2021 | Chinese Journal of Chemical Engineering2021，34，3： | 0 |
