tidy3d.plugins.autograd.invdes.ErosionDilationPenalty#

class ErosionDilationPenalty[source]#

Bases: Tidy3dBaseModel

A class that computes a penalty for erosion/dilation of a parameter map not being unity.

Parameters:

radius (Union[float, tuple[float, ...]]) – The radius of the kernel.
dl (Union[float, tuple[float, ...]]) – The grid spacing.
size_px (Optional[Union[int, tuple[int, ...]]] = None) – The size of the kernel in pixels.
beta (NonNegativeFloat = 20.0) – The beta parameter for the tanh projection.
eta (NonNegativeFloat = 0.5) – The eta parameter for the tanh projection.
filter_type (str = conic) – The type of filter to create.
padding (Literal['constant', 'edge', 'reflect', 'symmetric', 'wrap'] = reflect) – The padding mode to use.
delta_eta (float = 0.01) – The binarization threshold for erosion and dilation operations.
