For standard transmission, set all boundaries to . PML acts as an acoustic foam, absorbing outgoing waves without reflections.

Future work could include:

She used only on the thin waveguide core, saving hours of computation time by keeping the rest of the simulation "coarse." Chapter 3: The "Boundary" Breakthrough lumerical fdtd tutorial pdf

Always run a few simulations with increasingly finer meshes to ensure your results have converged to a stable value. For standard transmission, set all boundaries to

If your mesh is too coarse, the solver will miscalculate the refraction at interfaces. For standard transmission
