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 λ 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.
