Calculating the Far Field
Created OnOctober 13, 2022
Updated OnFebruary 19, 2025
By:Tony Golden
Once the current distribution on the structure has been calculated, the far-field can be computed within the angular ranges specified in the Far-Field panel of the Setup tab.
To calculate the far-field:
- Navigate to Run > Run Far-Field in the main menu (see Fig. 1).
- This command is enabled only after the current distribution has been calculated.
Tip
To sequentially and automatically calculate both the current distribution and the far field, click the Run Currents and Far-Field (F11) button on the toolbar.
