RF Material Library

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

>>> from tidy3d.plugins.microwave import rf_material_library

The key of the dictionary is the abbreviated material name.

Note: some materials have multiple variant models, in which case the second key is the “variant” name.

To import a material “mat” of variant “var”:

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

For example, Rogers3010 laminate can be loaded as:

>>> Rogers3010 = rf_material_library['RO3010']['design']

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

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

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

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

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

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