Anisotropic Magnetic Loss Tangent Tensors

The magnetic loss tangent tensor for an anisotropic material is described by

where

• tan d_M1 is the ratio of the imaginary relative permeability to the real relative permeability in one direction.



• tan d_M2 is the ratio of the imaginary relative permeability to the real relative permeability in the second direction.



• tan d_M3 is the ratio of the imaginary relative permeability to the real relative permeability in the third orthogonal direction.



• m'₁, m'₂, and m'₃ are the real relative permeabilities specified earlier.

The relationship between B and H will then be

To specify the magnetic loss tangent for an anisotropic material, enter the tan d_M1 , tan d_M2, and tan d_M3 values in the Value boxes of the T(1,1), T(2,2), and T(3,3) rows, respectively. These values can also be entered as functions.
