Anisotropic Dielectric Loss Tangent Tensors

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

where

• tan d₁ is the ratio of the imaginary relative permittivity to the real relative permittivity in one direction.



• tan d₂ is the ratio of the imaginary relative permittivity to the real relative permittivity in the second direction.



• tan d₃ is the ratio of the imaginary relative permittivity to the real relative permittivity in the third orthogonal direction.



• e'₁, e'₂, and e'₃ are the real relative permittivities specified earlier.

The relationship between D and E will then be

To specify the electric loss tangent for an anisotropic material, enter the tand₁, tand₂, and tand₃ 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 variables.
