class stable_pml#

Bases:

Stable PML boundary specification on both sides along a dimension.

Parameters:

  • num_layers (int = 40) – Number of layers of ‘stable’ PML to add to + and - boundaries.

  • parameters (PMLParams) – ‘Stable’ parameters of the complex frequency-shifted absorption poles.

Example

>>> stable_pml = Boundary.stable_pml(num_layers=40)
