Chapter 18 Dielectric Bricks
To define a new dielectric brick material, or to modify the characteristics of an existing
material, you use the Brick Materials dialog box, which is opened by selecting
Circuit ⇒ Brick Materials from the main menu of the project editor.
The Brick Materials dialog box, shown on page 269, shows all the dielectric brick
materials previously defined, the color/fill pattern assigned to each brick material,
and whether the material is isotropic or anisotropic. To modify the settings for a
particular dielectric brick material, edit that materials text entry boxes. Note that
for anisotropic materials all the parameters do not fit in the dialog box
simultaneously, so that it is necessary to use the scroll bars to access all settings.

If the brick type is isotropic only one set of parameters, X, will be set. Conversely,
if the brick material is set to anisotropic, each parameter is defined separately for
the X, Y, and Z dimensions. If you wish to make a brick material anisotropic, click
on the Ani checkbox.
The “default” material used when new dielectric bricks are created can also be set
in the Brick Materials dialog box. Select a brick type from the Default for add
bricks drop list. Once the default material has been set, all bricks created thereafter
will be made of that material.
Changing Brick Materials
The material type for bricks that already exist in a circuit can be changed by following
the procedure given below:
1 Select the brick(s) by clicking on it or lassoing it.
The brick is highlighted.
