Abstract
In this paper, we use an ISO-FDTD (improved shift operator finite-difference time-domain, proposed by others) algorithm to further process some more complex dielectric functions like critical models, and several higher order Lorentz models fitted by ourselves, these function models totally have 6 ~ 8 susceptibility terms, and each term was consisted by two complex poles (Lorentz model). Our working supporting the universal applicability of ISO-FDTD for processing higher-order complex dispersive materials. And we applied this ISO-FDTD algorithm in SFM-FDTD (split-field method FDTD) to simulate dispersion media under oblique incidence. The simulation results meet well with the analytical solutions. Researchers can have an alternate option besides ADE and PLRC methods when processing high-order dispersive media in SFM-FDTD.
