tidy3d.EMEFreqSweep#

class EMEFreqSweep[source]#

Bases: EMESweepSpec

Deprecated spec for sweeping frequency in the EME propagation step.

Parameters:

freq_scale_factors (ArrayLike[dtype=float, ndim=1]) – Deprecated approximate alternative to listing frequencies directly in EMESimulation.freqs. Scale factors are applied to every simulation frequency, and the new modes are then computed approximately using the exact modes as a basis. If there are multiple EMESimulation.freqs, the exact modes are computed at each of those frequencies and then scaled independently.
and (Prefer specifying the target frequencies directly in EMESimulation.freqs)
EMEModeSpec.interp_spec. (controlling the performance/accuracy tradeoff with)
mode (EMEFreqSweep is kept for backward compatibility and uses a perturbative)
modes. (solver relative to the simulation EME)

Example

>>> sweep_spec = EMEFreqSweep(freq_scale_factors=[0.9, 0.95, 1.0, 1.05, 1.1])
