tidy3d.PermittivityDataset

class PermittivityDataset

Bases: AbstractFieldDataset

Dataset storing the diagonal components of the permittivity tensor.

Parameters:

• eps_xx (Attribute: eps_xx) –

  Type	ScalarFieldDataArray
  Default
  Description	Spatial distribution of the xx-component of the relative permittivity.

• eps_yy (Attribute: eps_yy) –

  Type	ScalarFieldDataArray
  Default
  Description	Spatial distribution of the yy-component of the relative permittivity.

• eps_zz (Attribute: eps_zz) –

  Type	ScalarFieldDataArray
  Default
  Description	Spatial distribution of the zz-component of the relative permittivity.

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)
>>> sclr_fld = ScalarFieldDataArray((1+1j) * np.random.random((2,3,4,2)), coords=coords)
>>> data = PermittivityDataset(eps_xx=sclr_fld, eps_yy=sclr_fld, eps_zz=sclr_fld)

Attributes
