pml.apply_uniaxial_pml

pml.apply_uniaxial_pml​

Generate the permittivity and permeability tensor elements for uniaxial pml.

The PML assumes that the unit cell has primitive lattice vectors u and v which are parallel to x and y axes, respectively.

This function is appropriate for isotropic nonmagnetic media, but the permittivities and permeabilities generated are anisotropic.

Args:​

  • permittivity: isotropic permittivity
  • pml_params: The parameters defining the perfectly matched layer dimensions and absorption characteristics.

Returns:​

  • None: The permittivity and permeability tensor elements, ((permittivity_xx, permittivity_xy, permittivity_yx, permittivity_yy, permittivity_zz), (permeability_xx, permeability_xy, permeability_yx, permeability_yy, permeability_zz)).
