Using the Application Macro

Run the Create Edge Port application macro to create an edge port on a finite substrate. It creates a “bow-tie” structure given the specified parameters and adds an edge port.

1. Open a CADFEKO model containing a finite substrate.
2. Run the Create Edge Port application macro from the application macro library in CADFEKO.

   
   
   Figure 1. The Create Edge Port dialog.

3. In the Select configuration drop-down list, select a configuration. The frequency of the configuration is used to determine the edge length of the edge port.
4. In the Select part for union drop-down list, select the part that will be unioned with the “bow-tie” structure.
5. In the Specify points group, specify the named points to define the location of the edge port.

   Points A and B is used to determine the maximum width of the “bow-tie” structure.

   Point C determines the “height” of the “bow-tie” structure.

6. In the Specify edge port width group, select one of the following options:
   • using lambda
     • The edge port width is determined using lambda. By default, a value of $\frac{\lambda }{30}$ is used, but the value can be modified.
   • using width AB
     • The edge port width is determined using the physical width AB. By default, a value of (width AB)/7 is used, but the value can be modified.
7. Select the Add voltage source check box to add a voltage source after the port is created.
8. Click Create to run the script and to create the edge port.
