1基于FDTD的时域混合方法及其在天线前门耦合数值模拟中的应用显示文摘强电磁脉冲环境下的平台-机载天线一体化耦合计算属于典型多尺度时域电磁计算问题,采用传统的FDTD方法数值模拟时,由于精细结构的存在导致网格量巨大,计算效率低下。介绍了一种将非均匀FDTD方法与细导线FDTD方法以及多网格集总元件FDTD方法相结合的时域混合方法,能够有效降低计算开销,结合并行计算技术,快速计算得到天线端口上耦合产生的瞬态电压和电流响应,并将该方法成功应用于无人机平台-天线一体化前门耦合数值模拟中。鲍献丰 陈晓洁 李瀚宇 刘昌 周海京 2021强激光与粒子束2021,33,12:1
2FDTD technique based crosstalk analysis of bundled SWCNT interconnects显示文摘The equivalent electrical circuit model of a bundled single-walled carbon nanotube based distributed RLC interconnects is employed for the crosstalk analysis.The accurate time domain analysis and crosstalk effect in the VLSI interconnect has emerged as an essential design criteria.This paper presents a brief description of the numerical method based finite difference time domain(FDTD) technique that is intended for estimation of voltages and currents on coupled transmission lines.For the FDTD implementation,the stability of the proposed model is strictly restricted by the Courant condition.This method is used for the estimation of crosstalk induced propagation delay and peak voltage in lossy RLC interconnects.Both functional and dynamic crosstalk effects are analyzed in the coupled transmission line.The effect of line resistance on crosstalk induced delay,and peak voltage under dynamic and functional crosstalk is also evaluated.The FDTD analysis and the SPICE simulations are carried out at 32 nm technology node for the global interconnects.It is observed that the analytical results obtained using the FDTD technique are in good agreement with the SPICE simulation results.The crosstalk induced delay,propagation delay,and peak voltage obtained using the FDTD technique shows average errors of 4.9%,3.4%and0.46%,respectively,in comparison to SPICE.Yograj Singh Duksh Brajesh Kumar Kaushik Rajendra P.Agarwal 2015Journal of Semiconductors2015,36,5:0
