CPML derivatives use electric widths for forward differences and magnetic
|
|
|
|
|
widths for backward differences. `cpml_params(..., dx=1.0)` specifies the uniform
|
|
|
|
|
physical cell width normal to a face; arbitrary nonuniform PML grading is not
|
|
|
|
|
implemented by this constructor. Scale the timestep consistently with the grid.
