MaterialBirefringentSellmeier

class ansys.speos.core.input_files.material.MaterialBirefringentSellmeier(a=None, b=None, c=None, optical_class=MaterialOpticalClass.negative_uniaxial)

Bases: ansys.speos.core.input_files._base._ValueComparable

Dispersion of a birefringent material given by the Sellmeier coefficients.

Parameters:

a, b, cMaterialSellmeier, optional

Coefficients of the index along the a, b and c axes. By default, an independent ansys.speos.core.input_files.material.MaterialSellmeier model with its default coefficients per axis.

optical_classMaterialOpticalClass, optional

Optical class. By default, MaterialOpticalClass.negative_uniaxial.

Parameters:

• a (MaterialSellmeier | None)

• b (MaterialSellmeier | None)

• c (MaterialSellmeier | None)

• optical_class (MaterialOpticalClass)
