Defining dielectric material properties

From the menu bar in the Edit Material dialog box, select Electrical/MagneticDielectric (Electrical Permittivity).

(For information on displaying the Edit Material dialog box, see Creating or editing a material.)

Click the arrow to the right of the Type field, and specify the directional dependence of the dielectric constant.

Toggle on Use temperature-dependent data to define the dielectric constant as a function of temperature.

A column labeled Temp appears in the Data table.

Click the arrows to the right of the Number of field variables field to increase or decrease the number of field variables on which the dielectric constant depends.

Enter the applicable data in the Data table:

Dielectric constant

Dielectric constant for isotropic behavior. (Units of C$\phi$⁻¹L⁻¹.)

D11, D22, and D33

Three values to define orthotropic behavior, $D_{11}^{\phi \left(\epsilon \right)}$, $D_{22}^{\phi \left(\epsilon \right)}$, and $D_{33}^{\phi \left(\epsilon \right)}$. (Units of C$\phi$⁻¹L⁻¹.)

D11, D12, D22, D13, D23, D33

Six values to define anisotropic behavior, $D_{11}^{\phi \left(\epsilon \right)}$, $D_{12}^{\phi \left(\epsilon \right)}$, $D_{22}^{\phi \left(\epsilon \right)}$, $D_{13}^{\phi \left(\epsilon \right)}$, $D_{23}^{\phi \left(\epsilon \right)}$, $D_{33}^{\phi \left(\epsilon \right)}$. (Units of C$\phi$⁻¹L⁻¹.)

Temp

Temperature.

Field n

Predefined field variables.

You may need to expand the dialog box to see all the columns in the Data table. For detailed information on how to enter data, see Entering tabular data.

Click OK to close the Edit Material dialog box. Alternatively, you can select another material behavior to define from the menus in the Edit Material dialog box (see Browsing and modifying material behaviors, for more information).
