HFSS15: Anisotropic Relative Permeability Tensors

The permeability tensor for an anisotropic material is described by

where

• m₁ is the relative permeability along one axis of the material’s permeability tensor.

• m₂ is the relative permeability along the second axis.

• m₃ is the relative permeability along the third axis.

• m₀ is the permeability of free space.

The relationship between B and H is:

To specify the relative permeability for an anisotropic material, enter the m₁, m₂, and m₃ values in the Value boxes of the T(1,1), T(2,2), and T(3,3) rows, respectively. If the relative permeability is the same in all directions, use the same value for m₁, m₂, and m_3. These values can also be entered as variables.
