This paper deals with the time-domain numerical calculation of electromagnetic (EM) fields in media described by linear Drude dispersive models. The frequency-dependent finite-difference time-domain (FD2TD) method is applied to solve multipole Drude equations using equivalent circuit models. Two new different circuit methods, named as CIRC and PCRC, are proposed. The dispersion analysis and the stability conditions are carried out for these methods. Finally, illustrative examples are provided.

Abstract
This paper deals with the time-domain numerical calculation of electromagnetic (EM) fields in media described by linear Drude dispersive models. The frequency-dependent finite-difference time-domain (FD2TD) method is applied to solve multipole Drude equations using equivalent circuit models. Two new different circuit methods, named as CIRC and PCRC, are proposed. The dispersion analysis and the stability conditions are carried out for these methods. Finally, illustrative examples are provided.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
