HFSS15: Anisotropic Dielectric Loss Tangent Tensors
录入：edatop.com 点击：
The dielectric loss tangent tensor for an anisotropic material is described by
where
• tand1 is the ratio of the imaginary relative permittivity to the real relative permittivity in one direction.
• tand2 is the ratio of the imaginary relative permittivity to the real relative permittivity in the second direction.
• tand3 is the ratio of the imaginary relative permittivity to the real relative permittivity in the third orthogonal direction.
• 
, 
, and 
are the real relative permittivities specified earlier.e
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.
