Anisotropic Conductivity Tensors
The conductivity tensor for an anisotropic material is described by
where
- s1 is the relative conductivity along one axis of the material’s conductivity tensor.
- s2 is the relative conductivity along the second axis.
- s3 is the relative 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.
