Lumerical Fdtd Tutorial Portable

Next came boundary conditions. The tutorial had awoken her to the importance of perfectly matched layers and symmetry planes. She enabled mirror symmetry to halve the domain—there had been advice about speed versus artifact. This time, the symmetry nudged the simulation, and the resonance grew clearer, but its Q factor was lower than expected. Absorption at the edges? Numerical leakage? She adjusted the PMLs, extended them, tuned their decay. The peak grew narrower, as if the cavity itself were learning to hold light more tightly.
