Material Library

The material library is a dictionary containing various dispersive models from real world materials. To use the materials in the library, import it first by:

>>> from tidy3d import material_library

The first key of the dictionary is the material name (abbreviated), the second key is the “variant” name, which indicates the data source. In the material library below, the material names (abbreviated) are in parentheses in the header and the variant names are in the table.

To import a material “mat” of variant “var” as a tidy3d medium:

>>> medium = material_library['mat']['var']

For example, silver measured by A. D. Rakic et al. (1998) can be loaded as:

>>> silver = material_library['Ag']['Rakic1998BB']

You can also import the default variant of a material by:

>>> medium = material_library['mat'].medium

Note: it is often useful to see the full list of variants for a given medium:

>>> print(material_library['mat'].variants.keys())

To access the details of a variant, including material model, references and tabulated data, use the following command:

>>> material_library['mat'].variants['var']
