flex_rf.tidy3d.SurfaceImpedance

Type: class Base(s): PECConformal

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

edge_singularity_correction [bool] = True

Apply field correction model at metallic edges where field singularity occurs. The edges should be straight, and aligned with the primal grids; and the wedge angle is either 0 or 90 degree.

timestep_reduction [float] = DEFAULT_COURANT_REDUCTION_SIBC_CONFORMAL

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.
