tidy3d.EMEFreqSweep

class EMEFreqSweep

Bases: EMESweepSpec

Spec for sweeping frequency in EME propagation step. Unlike sim.freqs, the frequency sweep is approximate, using a perturbative mode solver relative to the simulation EME modes. This can be a faster way to solve at a larger number of frequencies.

Parameters:

freq_scale_factors (ArrayLike[dtype=float, ndim=1]) – Scale factors applied to every frequency in ‘EMESimulation.freqs’. After applying the scale factors, the new modes are 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 the scale factors are applied to each independently.

Example

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