摘要:
提出了一种改进FDTD(Finite Difference Time Domain)仿真结果的等效宽度技术,它通过对仿真对象的尺寸进行加权修正,即使在使用粗网格进行FDTD仿真时也能得到准确的结果.同时对FDTD仿真时节省运算时间和存储空间也具有非常实用的价值.并通过对均匀微带线的特性阻抗和贴片天线、低通滤波器的散射系数的计算验证了这一理论.
Abstract:
In th is paper, a fast convergent techn ique w as presented. An improved accurate FDTD ( F inite D ifference T im e Dom a in) s imu la tion resu lt cou ld be g enerated using a relatively coarsem esh fo r PEC planar structures if an e ffective factor is proper ly selected. It is ve ry va luab le because the ca lcu lating time and space cou ld be decreased when FDTD simu lation is done. A m icrowave patch antenna and a low pass filterw ere used in th is pape r to ver ify the proposed schem e.
