abstract = {<p style="text-align: justify;">In this paper, we develop and analyze finite difference methods for the 3D Maxwell&#39;s
equations in the time domain in three different types of linear dispersive media described as Debye,
Lorentz and cold plasma. These methods are constructed by extending the Yee-Finite Difference
Time Domain (FDTD) method to linear dispersive materials. We analyze the stability criterion
for the FDTD schemes by using the energy method. Based on energy identities for the continuous
models, we derive discrete energy estimates for the FDTD schemes for the three dispersive models.
We also prove the convergence of the FDTD schemes with perfect electric conducting boundary
conditions, which describes the second order accuracy of the methods in both time and space. The
discrete divergence-free conditions of the FDTD schemes are studied. Lastly, numerical examples
are given to demonstrate and confirm our results.</p>},
