class tidy3d.PermittivityData#

Bases: tidy3d.components.data.dataset.PermittivityDataset, tidy3d.components.data.monitor_data.AbstractFieldData

Data for a PermittivityMonitor: diagonal components of the permittivity tensor.

Parameters

monitor (PermittivityMonitor) – symmetry : Tuple[Literal[0, -1, 1], Literal[0, -1, 1], Literal[0, -1, 1]] = (0, 0, 0) Symmetry eigenvalues of the original simulation in x, y, and z.
symmetry_center (Optional[Tuple[float, float, float]] = None) – Center of the symmetry planes of the original simulation in x, y, and z. Required only if any of the symmetry field are non-zero.
grid_expanded (Optional[Grid] = None) – Grid on which the symmetry will be expanded. Required only if any of the symmetry field are non-zero.
eps_xx (ScalarFieldDataArray) – Spatial distribution of the xx-component of the relative permittivity.
eps_yy (ScalarFieldDataArray) – Spatial distribution of the yy-component of the relative permittivity.
eps_zz (ScalarFieldDataArray) – Spatial distribution of the zz-component of the relative permittivity.

Example

>>> from tidy3d import ScalarFieldDataArray
>>> 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)
>>> sclr_fld = ScalarFieldDataArray((1+1j) * np.random.random((2,3,4,2)), coords=coords)
>>> monitor = PermittivityMonitor(size=(2,4,6), freqs=[2e14, 3e14], name='eps')
>>> data = PermittivityData(monitor=monitor, eps_xx=sclr_fld, eps_yy=sclr_fld, eps_zz=sclr_fld)
