Abstract:
In this report we consider the Debye model along with Maxwell's equations (Maxwell-
Debye) to model electromagnetic wave propagation in dispersive media that exhibit
orientational polarization. We construct and analyze a sequential operator splitting
method for the discretization of the Maxwell-Debye system. Energy analysis indicates
that the operator splitting scheme is unconditionally stable. We also conduct a trun-
cation error analysis to show that the scheme is rst order accurate in time and second
order accurate in space. We compare the operator splitting method to the Yee scheme
for discretizing the Maxwell-Debye system via stability, dispersion, and dissipation
analyses. Numerical simulations validate the unconditional stability of the scheme.
