A unified unconditionally stable split-step finite difference time domain SS-FDTD) algorithm is presented for modeling general multi-term dispersive electromagnetic applications. The algorithm is based on the exponential evolution operator (EEO) scheme and the split-step FDTD formulations. The proposed approach has the dvantage of being 1) more systematic allowing the treatment of different types of linear dispersive
dielectric media in the same manner and 2) can be easily incorporated with the perfectly matched layer absorbing boundary conditions to model open
region problems. Numerical example is included to the validity of the proposed algorithm.
