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.
