How do I use a dielectric material from a dielectric library?

Dielectric Layers

To use a dielectric material from the metal library in your circuit, do the following:

1. Select Circuit => Dielectric Layers from the main menu of the project editor.
   
   The Dielectric Layers dialog box is opened on your display. This dialog box allows you to add, edit and delete dielectric layers for your project.

2. Click on an existing dielectric layer to select it.
   
   There are always two default dielectric layers in a new geometry project.

3. Click on the Above or Below button to add a dielectric layer to your project.
   
   This opens the Dielectric Editor dialog box which allows you to define a dielectric layer or input a dielectric material from your library to use for the dielectric layer.
   
   You could also have clicked on the Edit button which would open the presently selected layer in the Dielectric Editor dialog box.
   
   The dielectric layer will be added above or below the presently selected dielectric layer.
   
   Note: Clicking on the Library button in the Dielectric Layers dialog box allows you edit the contents of your dielectric libraries but does not allow you to add dielectric materials from the library to your project. This must be done in the Dielectric Editor dialog box.

4. Click on the Select Dielectric from Library button in the Metal Editor dialog box.
   
   The Dielectric Library dialog box appears on your display.

5. Select the My Library or Global library by clicking on the appropriate radio button in the Dielectric Library dialog box.
   
   If you wish to select a new library file, click on the Specify button to the right of the radio button which opens a browse window which allows you to select a file. For instructions on setting up a library, see How do I Set up a dielectric library?
   
   Once a library is selected, a list of dielectric materials in the library should appear in the dialog box.

6. Click on the desired dielectric material to select it.
   
   The entry is highlighted.

7. Click on OK in the Dielectric Library dialog box.
   
   This selects the dielectric material and closes the dialog box. The Dielectric Editor text entry boxes now contain the material name and loss parameters from the library dielectric you selected.

8. Enter the desired thickness for the dielectric layer in the Thickness text entry.
   
   You may also edit the thickness of the dielectric layer in the Dielectric Layers dialog box.

9. Enter the desired number of copies in the Number of Copies text entry box.
   
   You may enter multiple dielectric layers at one time by using this field. Each dielectric layer will be of the thickness specified here and use the same loss parameters.

10. Click on the OK button in the Dielectric Editor dialog box.
    
    The Dielectric Editor dialog box is closed and an entry for the dielectric layer just entered appears in the list in the Dielectric Layers dialog box.

11. Click on the OK button in the Dielectric Layers dialog box to close the box and apply the changes.
    
    This completes adding a dielectric layer using a dielectric material from the library.
