class EMELengthSweep[source]#

Bases: EMESweepSpec

Spec for sweeping EME cell lengths.

  • attrs (dict = {}) – Dictionary storing arbitrary metadata for a Tidy3D object. This dictionary can be freely used by the user for storing data without affecting the operation of Tidy3D as it is not used internally. Note that, unlike regular Tidy3D fields, attrs are mutable. For example, the following is allowed for setting an attr obj.attrs['foo'] = bar. Also note that Tidy3D` will raise a TypeError if attrs contain objects that can not be serialized. One can check if attrs are serializable by calling obj.json().

  • scale_factors (Union[ArrayLike[dtype=float, ndim=1], ArrayLike[dtype=float, ndim=2]]) – Length scale factors to be used in the EME propagation step. The EME propagation step is repeated after scaling every cell length by this amount. The results are stored in ‘sim_data.smatrix’. If a 2D array is provided, the first index is the sweep index and the second index is the cell index, allowing a nonuniform cell scaling along the propagation axis.



Number of sweep indices.
