pmrf.materials.as_dielectric(value) → AbstractDielectric

Coerce a value into a dielectric material.

Accepts an existing AbstractDielectric, a scalar permittivity, or an (ep_r, tand) or (ep_r, tand, sigma) tuple, which build a ConstantDielectric.

Parameters:

Returns:

The resulting dielectric material.

Return type:
