The CFS values (which are internally specified) used for the default standard first order PML are: ``#pml_cfs: constant forward 0 0 constant forward 1 1 quartic forward 0 None``. Specifying 'None' for the maximum value of :math:`\sigma` forces gprMax to calculate it internally based on the relative permittivity and permeability of the underlying materials in the model.

The parameters will be applied to all slabs of the PML that are switched on.

``forward`` direction implies minimum parameter value at the inner boundary of the PML and maximum parameter value at the edge of computational domain, ``reverse`` is the opposite. ``forward`` direction implies minimum parameter value at the inner boundary of the PML and maximum parameter value at the edge of computational domain, ``reverse`` is the opposite.
