Absorbs outgoing waves to simulate infinite open space. Use "Steep Angle" or "Stretch PML" for grazing incidence angles.
| Problem | Likely Cause from PDF Steps | Solution | | :--- | :--- | :--- | | | Auto-shutoff level too low or PML thickness insufficient. | Increase PML layers to 12; set shutoff to 1e-5 initially. | | Transmission > 100% | Source normalization monitor missing or incorrectly placed. | Ensure the reference monitor is before any scattering structure. | | Slow simulation | Global mesh override is too fine. | Use mesh override only in regions with high field gradients (e.g., metal-dielectric interfaces). | | Wrong resonance frequency | Simulation time is too short. | Extend simulation end time to 10,000 fs for high-Q cavities. | lumerical fdtd tutorial pdf top
