: Because it operates in the time domain, a single simulation can yield results across a wide range of frequencies. Scalability Select as the printer destination

Use for infinitely repeating structures like metasurfaces or photonic crystals.

Use on boundaries where light should exit without reflecting. Choose the "Stretched Coordinate PML" profile for steep angles.
