Post-processing is where the tutorial shines. Users learn to place and power transmission boxes . A classic exercise involves simulating a silicon-on-insulator (SOI) waveguide taper: the user calculates transmission as a function of taper length, then uses the script interface to export S-parameters.
She tightened the mesh. The tutorial’s notes whispered in her memory about spatial discretization and dispersion—“refine where fields vary rapidly.” She increased the mesh inside the defect and around the holes, pushing the simulation cost higher. Hours later, the spectrum sharpened. One small peak that had been a smear began to stand out. She leaned forward. lumerical fdtd tutorial
Drag the FDTD region from the toolbar.
The phantom mode hummed on-screen, a small victory of light and patience. Post-processing is where the tutorial shines
For most nanophotonic applications, use a or a Total-Field Scattered-Field (TFSF) source. Define the wavelength range (e.g., 400nm to 700nm). She tightened the mesh
