The dielectric libraries contain standard definitions of dielectric materials which may be used for your dielectric layers. There are two types of dielectric libraries available in Sonnet: global and local. There is no real difference between the two libraries. The names refer to the way in which they are used.
NOTE: The Dielectric Libraries materials may not be used for dielectric bricks but only for dielectric layers.
The global library would usually be used as a group wide library of standard dielectrics for a group of designers.There is a default global library supplied by Sonnet which contains definitions for dielectric materials. The default location for the global library is in <Sonnet Data Directory>/data/libraries where <Sonnet Data Directory> is the directory in which your Sonnet software data is installed. You may choose to use this location or can save this library in another location.
The local library would usually be used as the user's own library of dielectric material definitions. This library may be stored in a location of the user's choice. You use the Dielectric Editor dialog box to add, edit and delete entries to these libraries.
