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.
