tidy3d.SurfaceImpedance

tidy3d.SurfaceImpedance#

class SurfaceImpedance[source]#

Bases: PECConformal

Apply 1st order (Leontovich) surface impedance boundary condition to structure made of LossyMetalMedium.

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().

  • timestep_reduction (ConstrainedFloatValue = 0.0) – Reduction factor between 0 and 1 such that the simulation’s time step size is 1 - timestep_reduction times its default value. Accuracy can be improved with a smaller time step size, but the simulation time will be increased.
