tidy3d.DefaultAbsorberParameters#

tidy3d.DefaultAbsorberParameters = AbsorberParams(sigma_order=3, sigma_min=0.0, sigma_max=6.4, type='AbsorberParams')#

Specifies parameters common to Absorbers and PMLs.

Parameters

  • sigma_order (NonNegativeInt = 3) – Order of the polynomial describing the absorber profile (~dist^sigma_order).

  • sigma_min (NonNegativeFloat = 0.0) – [units = 2*EPSILON_0/dt]. Minimum value of the absorber conductivity.

  • sigma_max (NonNegativeFloat = 1.5) – [units = 2*EPSILON_0/dt]. Maximum value of the absorber conductivity.

Example

>>> params = AbsorberParams(sigma_order=3, sigma_min=0.0, sigma_max=1.5)
