Exporting the Far Field

To perform post-processing in external software or for detailed documentation, AN-SOF allows you to tabulate and export both spatial patterns and frequency spectra.

Available Export Commands

Navigate to the Results menu to access the following options:

• List Far-Field Pattern: Displays the spatial distribution of the radiation (gain, directivity, or field strength) at a specific frequency for a range of angles (Theta, Phi).
• List Far-Field Spectrum: Displays the far-field results across the entire simulated frequency range for a fixed observation direction (Theta, Phi).

The Results Table

Once you execute a command, a results window will appear (Fig. 1). This table includes:

• Angles: Theta and Phi coordinates.
• Electric Field Components: E-total, E-theta, E-phi, E-right, E-left (real and imaginary parts as well as magnitudes and phases).
• Axial Ratio: The axial ratio of the field polarization ellipse (dimensionless and in decibels).

Saving Data

To save this information for use in Excel, MATLAB, or Python:

1. Click the Export button of the results window (Fig. 1).
2. Choose a destination and save the file in CSV (Comma Separated Values) format.
