Exporting the Near Field

For users who need to perform external numerical analysis or generate reports, AN-SOF provides a straightforward way to move near-field data into tools like Excel, MATLAB, or Python.

Available Export Commands

Access these options via the Results menu. Depending on whether you need spatial data (at a specific frequency) or frequency data (at a specific point), choose from the following:

• List Near E-Field/H-Field/Power Density Pattern: Displays a table of the electric field ($\mathbf{E}$), magnetic field ($\mathbf{H}$), or power density ($S = |\mathbf{E} \times \mathbf{H}^*|$) across your entire grid for a single frequency.
• List Near E-Field/H-Field/Power Density Spectrum: Displays the field behavior across all simulated frequencies for a single, fixed coordinate point.

The Results Table

Executing these commands opens a data window containing the raw numerical results. The table format adapts to your chosen coordinate system:

Column Type	Description
Coordinates	The position $(x, y, z)$, $(\rho, \phi, z)$, or $(r, \theta, \phi)$.
Total Field	The total RMS magnitude of the field at that location/frequency.
Field Components	Magnitude and Phase for each vector component (e.g., $E_x, E_y, E_z$).

Saving to CSV

To export this data:

1. Click the Export button on the right side of the table.
2. Specify your file name and save it as a .csv file.

This format is universally compatible and allows you to recreate high-resolution heat maps or perform safety compliance calculations in third-party software.
