flex_rf.tidy3d.PMLParams

Type: class │ Base(s): AbsorberParams

Description

Specifies full set of parameters needed for complex, frequency-shifted PML.

params = PMLParams(sigma_order=3, sigma_min=0.0, sigma_max=1.5, kappa_min=0.0)

sigma_order [NonNegativeInt] = 3

Order of the polynomial describing the absorber profile ( $\mathrm{dist}^{\text{sigma\_order}}$ ).

sigma_min [NonNegativeFloat] = 0.0

Minimum value of the absorber conductivity.

sigma_max [NonNegativeFloat] = 1.5

Maximum value of the absorber conductivity.

kappa_order [NonNegativeInt] = 3

Order of the polynomial describing the PML kappa profile ( $\kappa\sim\mathrm{dist}^{\text{kappa\_order}}$ ).

kappa_min [NonNegativeFloat] = 0.0

kappa_max [NonNegativeFloat] = 1.5

alpha_order [NonNegativeInt] = 3

Order of the polynomial describing the PML alpha profile ( $\alpha\sim\mathrm{dist}^{\text{alpha\_order}}$ ).

alpha_min [NonNegativeFloat] = 0.0

Minimum value of the PML alpha.

alpha_max [NonNegativeFloat] = 1.5

Maximum value of the PML alpha.
