Brick Editor dialog box

The Brick Editor dialog box is opened when you click on the Add Brick or Edit button in the Brick dielectrics tab of the Materials page of the Circuit Settings dialog box. This dialog box allows you to enter the parameters of a brick dielectric in order to define a dielectric material for use in your circuit.

 Misuse of dielectric bricks can lead to significantly inaccurate results. It is highly recommended that you read the entire Dielectric Bricks chapter in the Sonnet User's Guide before attempting to use dielectric bricks.

The dielectric defined here is to be used for a dielectric brick in your circuit. Note that a dielectric brick uses the Mrel and Mag Loss Tan parameters of the dielectric layer in which it is embedded. Therefore, there are no fields present for these two values.

Mat. Name: Enter the desired name for the dielectric material to be used in a dielectric brick here.

Specify Using: You may chose to define your dielectric brick loss using Conductivity, or Resistivity. Select whichever value you have available for your dielectric material. The dialog box is updated to include a text entry box for whichever choice you make in the drop list.

Pattern: Use the arrow buttons to step through the available display patterns you may assign to this brick material. This pattern is used to identify this dielectric brick material when it is used in your circuit.

Anisotropic: If you wish the brick material to be anisotropic, indicating that its parameters are different in each dimension, click on this checkbox. The dialog box is updated so that there are three sets of entries; one each for the x, y and z direction. You can then enter the parameters of the brick material by editing the entries in the row.

Erel: Enter the relative dielectric constant here.

Dielectric Loss Tan: Enter the dielectric loss tangent here.

Conductivity: Enter the dielectric conductivity here. This text entry box only appears when "Conductivity" is selected in the Specify Using drop list.

Resistivity: Enter the dielectric resistivity here. This text entry box only appears when "Resistivity" is selected in the Specify Using drop list.

Enter the appropriate value for each parameter in its text entry box.  How do I specify loss in a dielectric brick?  Using Variables in this dialog box
