Lumerical Fdtd Tutorial -

Perhaps the most critical practical skill is the placement of Perfectly Matched Layers (PMLs). The tutorial includes a dedicated module showing how to position PMLs at least half a wavelength away from scatterers to avoid evanescent-field interactions. It also contrasts PML with periodic (Bloch) boundaries for metasurface simulations and metal boundaries for plasmonic waveguides.

We will simulate a simple operating at 1550 nm. lumerical fdtd tutorial
