HFSS15: Anisotropic Relative Permittivity Tensors
录入：edatop.com 点击：
The permittivity tensor for an anisotropic material is described by
where
• e1 is the relative permittivity of the material along one tensor axis.
• e2 is the relative permittivity along the second axis.
• e3 is the relative permittivity along the third axis.
• e0 is the permittivity of free space.
The relationship between E and D is then
To specify the relative permittivity for an anisotropic material, enter the e1, e2, and e3 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.
