    Calculating the Near H-Field

    Created On
    Updated On
    By:Tony Golden

    Once the current distribution on the structure has been calculated, the near magnetic field can be computed at the points in space specified in the Near-Field panel of the Setup tab.

    To calculate the near magnetic field:

    • Navigate to Run > Near H-Field in the main menu (see Fig. 1).
      • This command is enabled only after the current distribution has been calculated.
    Fig. 1: The “Near H-Field” command in the Run menu.

    💡 Tips

    • To sequentially and automatically calculate both the current distribution and the near fields, click the Run Currents & Near-Fields (F11) button on the toolbar. This command also calculates the near E-Field.
    • To enable the calculation of the H-Field, go to Tools > Preferences > Options tab in the main menu and check the Include H-field in “All Metrics” calculation option.

    📝 Note:

    When an incident plane wave is used as the excitation, the calculated near-field results represent the scattered fields.
