Creating an Anisotropic Medium (Diagonalised Tensor)

Create an anisotropic medium by defining the diagonal permittivity tensor and diagonal permeability tensor.

Tip: Create up to three dielectrics constituting the medium properties along the UU axis, VV axis and NN axis.
  1. On the Construct tab, in the Define group, click the  Media icon. From the drop-down list, select the  Anisotropic (3D) icon.


    Figure 1. The Create Anisotropic Dielectric dialog (Diagonalised tensor).
  2. In the Tensor type field, from the drop-down list select Diagonalised tensor.
  3. For each diagonal entry, select one of the following options:
    • To use the medium properties of free space, from the drop-down list select Free space.
    • To indicate that no linear dependencies exist between the two axes, from the drop-down list select 0.
    • To use the medium properties of a predefined dielectric, from the drop-down list, select the dielectric.
    • To use the medium properties of a dielectric, which is not yet defined in the model, click the icon to define the dielectric or add a dielectric from the media library.
  4. [Optional] In the Mass density (kg/m^3) field, enter a value for ρ.
  5. Click Create to create the anisotropic medium and to close the dialog.
