HFSS15: Anisotropic Conductivity Tensors

The conductivity tensor for an anisotropic material is described by

where

• s₁ is the conductivity along one axis of the material’s conductivity tensor.

• s₂ is the conductivity along the second axis.

• s₃ is the conductivity along the third axis.

The relationship between J and E is then:

To specify the conductivity for an anisotropic material, enter the s₁, s₂, and s₃ values in the Value boxes of the T(1,1), T(2,2), and T(3,3) rows, respectively. The values of s₁ and s₂ apply to axes that lie in the xy cross-section being modeled. The values of s₃ apply to the z-component. These values affect current flowing in dielectrics between the conductors. These values can also be entered as variables.
