Creating an Anisotropic Medium (Ferrite)

Create a ferrimagnetic medium. The medium is described by the permittivity and permeability tensors where the static magnetic field is orientated along the U axis, V axis and N axis respectively.

1. On the Construct tab, in the Define group, click the  Media icon. From the drop-down list, select the  Anisotropic (3D) icon.
2. In the Tensor type field, from the drop-down list select Polder tensor (ferrites).
3. Specify the magnetic properties.
1. Under Medium properties, in the Saturation magnetisation (Gauss) field, enter a value for 4 $\pi$ Ms.
2. Under Medium properties, in the Line width (Oersted) field, enter a value for ΔH.
3. Under Magnetostatic bias field, in the DC bias field (Oersted) field, enter a value for H0.
4. Under Magnetostatic bias field, from the Field direction drop-down list, select one of the following:
• X directed
• Y directed
• Z directed
4. Specify the dielectric properties.
1. In the Relative permittivity field, enter a value for εr.
2. In the Dielectric loss tangent field, enter a value for tanδ.
5. In the Label field, enter a unique label for the ferrite medium.
6. Click Create to create the anisotropic medium and to close the dialog.
