摘要:
介绍了色散介质的移位算子时域有限差分方法(SO-FDTD).通过将色散介质的介电常数写成有理分式函数形式,推导出时域中电位移矢量D和电场强度E之间的关系,将此方法应用于计算电磁波在均匀非磁化等离子体中的传播.与ZT-FDTD方法计算的结果相比,SO-FDTD方法的计算精度得到了证实,数值结果进一步显示出这一算法计算效率高,消耗的计算机资源少.
Abstract:
The sh ift opera tor finite-d ifference tim e-dom ain( SO-FDTD) m ethod is presented for d ispersive m ed ia. The perm ittiv ity o f dispers ive med ia is w r itten as rational polynom ia l function. The relation betw een D and E is der ived in tim e dom a in. In th is paper, the SO-FDTD m ethod is applied to sim ulate the e lectrom agnetic w ave propag ation in hom ogeneous unm agne tized plasma. The accu racy of the m ethod is verified by compar ing the so lution of ZT-FDTD. TheNum erical resu lts a lso show that the SO-FDTD m ethod is v ery e fficient and its calculation occupies few er com puter resources.
