tidy3d.SkinDepthFitterParam

class SkinDepthFitterParam

Bases: Tidy3dBaseModel

Advanced parameters for fitting complex-valued skin depth 2j/k of a LossyMetalMedium over its frequency bandwidth, where k is the complex-valued wavenumber inside the lossy metal. Real part of this quantity corresponds to the physical skin depth.

Parameters:

• attrs (dict = {}) – Dictionary storing arbitrary metadata for a Tidy3D object. This dictionary can be freely used by the user for storing data without affecting the operation of Tidy3D as it is not used internally. Note that, unlike regular Tidy3D fields, attrs are mutable. For example, the following is allowed for setting an attr obj.attrs['foo'] = bar. Also note that Tidy3D` will raise a TypeError if attrs contain objects that can not be serialized. One can check if attrs are serializable by calling obj.json().

• max_num_poles (PositiveInt = 3) – Maximal number of poles in complex-conjugate pole residue model for fitting complex-valued skin depth.

• tolerance_rms (NonNegativeFloat = 0.001) – Tolerance in fitting complex-valued skin depth.

• frequency_sampling_points (PositiveInt = 20) – Number of sampling frequencies used in fitting.

• log_sampling (bool = True) – Whether to sample frequencies logarithmically (True), or linearly (False).
