Abstract:
In this work we analyze several two-stage split-step
finite-difference time-domain (2SS-FDTD) schemes and compare
their performance with that of the traditional FDTD formulation.
We present the numerical dispersion relations and the local
truncation errors. All the schemes studied show error terms that
depend on the time step multiplied by the spatial derivatives. We
show that these error terms are especially critical in the locally
one-dimensional (LOD)-FDTD scheme. To illustrate the relevance
of these terms we simulate the propagation of the fundamental
mode in a rectangular waveguide with a narrow iris.
