Calculating the Port Reflections and Field Data

Use the Multiport post-processing application macro in POSTFEKO to calculate the port reflections and field data for a model (plate4prt.fek) with different load configurations.

1. Open POSTFEKO and run the Multiport post-processing application macro from the application macro library.
   The Multiport post-processing dialog is displayed.
2. Specify the input method for the Multiport post-processing application macro.
   For this example, a Feko model (plate4prt.fek) is used as input.

   Tip: Find the examples in the <FEKO_SHARED_HOME> directory:

   %FEKO_SHARED_HOME%/installedapplicationmacrolibrary/POSTFEKO/MultiportCalculation/examples.

   1. Under Definition method, select Feko model.
   2. In the Model field, browse to the file location of plate4prt.fek.
