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.
-
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). - In the Tensor type field, from the drop-down list select Diagonalised tensor.
-
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.
- [Optional] In the Mass density (kg/m^3) field, enter a value for ρ.
- Click Create to create the anisotropic medium and to close the dialog.
