tidy3d.components.data.dataset.FieldDataset

class FieldDataset

Bases: ElectromagneticFieldDataset

Dataset storing a collection of the scalar components of E and H fields in the freq. domain

Parameters:

• 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().

• Ex (Optional[ScalarFieldDataArray] = None) – Spatial distribution of the x-component of the electric field.

• Ey (Optional[ScalarFieldDataArray] = None) – Spatial distribution of the y-component of the electric field.

• Ez (Optional[ScalarFieldDataArray] = None) – Spatial distribution of the z-component of the electric field.

• Hx (Optional[ScalarFieldDataArray] = None) – Spatial distribution of the x-component of the magnetic field.

• Hy (Optional[ScalarFieldDataArray] = None) – Spatial distribution of the y-component of the magnetic field.

• Hz (Optional[ScalarFieldDataArray] = None) – Spatial distribution of the z-component of the magnetic field.

Example

>>> x = [-1,1]
>>> y = [-2,0,2]
>>> z = [-3,-1,1,3]
>>> f = [2e14, 3e14]
>>> coords = dict(x=x, y=y, z=z, f=f)
>>> scalar_field = ScalarFieldDataArray((1+1j) * np.random.random((2,3,4,2)), coords=coords)
>>> data = FieldDataset(Ex=scalar_field, Hz=scalar_field)
