  However, the software's power is matched by its complexity. This aims to bridge the gap between theory and practice. By the end of this guide, you will understand the core workflow, from geometry setup to data extraction. Ansys Lumerical FDTD This draft post provides a

  1. Create FDTD region (size: 2 µm cube, PML all directions)
  2. Add glass substrate (n=1.46, thickness 200 nm)
  3. Add gold nanodisk (radius 100 nm, height 50 nm) – use Au (CRC) material
  4. Add TFSF source (plane wave, λ=400–800 nm, from top)
  5. Add transmission monitor (under disk) and reflection monitor (above)
  6. Add field monitor (x-z plane)
  7. Run simulation
  8. Plot: Extinction = 1 – T – R
  9. Visualize near-field enhancement at resonance

  As the fields stabilized, the "noise" he saw earlier vanished. By following the rigorous steps of a proper workflow , Aris saw the light coupling perfectly into the side-branch. The transmission graph showed a sharp, clean peak right at his target wavelength.

  Monitors

  : Place frequency-domain or time-domain monitors to collect data like transmission, reflection, and field profiles.
