RF Material Library

The RF material library is a dictionary of dispersive models for common RF metals, laminates, ceramics, and dielectrics. Import it from flex_rf.tidy3d and access a material by key and variant.

from flex_rf.tidy3d import rf_material_library

rogers_3010 = rf_material_library["RO3010"]["design"]
default_duroid = rf_material_library["RT_duroid5880"].medium
duroid_range = rf_material_library["RT_duroid5880"].medium_in_range(
    frequency_range=(5e9, 10e9),
)

Some entries expose multiple variants. Use variants.keys() to inspect them.

print(rf_material_library["RO3010"].variants.keys())
print(rf_material_library["RO3010"].variants["design"])
