How do I define a brick material?

Geometry Elements - Dielectric Bricks

To define a new dielectric brick material in Sonnet, do the following:

1.   Select Circuit => Brick Materials from the project editor main menu.

2.   The Brick Materials dialog box appears. Click on the Add button. The Dielectric Editor dialog box appears on your display with a new material with the name ''Brick 1''.

3.   If you wish to change the name, edit the Name text entry box.

4.   If you do not want to use the default fill pattern provided, click on the up or down arrow in the pattern field until you find a cell fill pattern you wish to use for this brick material.

5.   Enter the parameters for the brick material in the appropriate text entry boxes.

A brick material specifies the dielectric constant (Erel), dielectric loss tangent and bulk conductivity used by em, and whether the dielectric is isotropic or anisotropic. If the brick material is isotropic you only need to enter the dielectric constant, dielectric loss tangent and bulk conductivity once in the first three text entry boxes. These values are used for all three directions: x, y and z. If the material is anisotropic, you should click on the Anisotropic checkbox and fill in the parameters for all three directions. For more information about how the parameters are used to model loss for a dielectric brick, see How do I specify loss in a dielectric brick?

6.   When you have completed defining the dielectric material, click on the OK button to close the dialog box. This dielectric material now appears in the list in the Brick Materials dialog box.

7.   Click on the OK button in the Brick Materials dialog box to close the dialog box and apply the changes. This new brick material is now available to be used for bricks anywhere in your circuit.
