A complete framework for the modeling of linear and nonlinear dispersion effects with FDTD

The presented approach can treat any combination of the linear Drude, Debye and Lorentz models and the nonlinear Kerr- and Raman-effects with the finite-difference time-domain (FDTD) method. The algorithms have been implemented and tested in an FDTD software using several benchmark problems. Moreover, the software has been equipped with new strategies to address the challenges in FDTD when dealing with dispersive materials.
