    The 3D-View Interface

    Created On
    Updated On
    By:Tony Golden

    The 3D-View interface provides an intuitive, graphical method for configuring incident field parameters, allowing you to visualize the direction and polarization of the incoming wave relative to your structure.

    Step-by-Step Configuration

    1. Activate Incident Field: Go to the Setup tab and select the Incident Field option within the Excitation panel.
    2. Launch the Interface: Click the 3D View button. This opens the 3D-View window along with the Incident Wave dialog box (Fig. 1).
    3. Adjust Angles: Enter your desired values for Gamma, Theta, and Phi, then press ENTER. Alternatively, you can use the incremental arrows to fine-tune these angles while observing the visual representation in the 3D space.
    4. Confirm and Sync: Close the Incident Wave dialog box. The values you set graphically are automatically synchronized and will now appear in the Excitation panel of the main interface (Fig. 2).
    Fig. 1: 3D-View interface for the definition of the incident field, featuring the Incident Wave dialog box. In this configuration, the parameters are set to $\gamma = -45^\circ$, $\theta = 45^\circ$, and $\phi = -100^\circ$.
    Fig. 2: The Gamma ($\gamma$), Theta ($\theta$), and Phi ($\phi$) angles entered in the Incident Wave dialog box are automatically synchronized and will appear in the Excitation panel of the Setup tab.

    Why Use 3D-View?

    Using the graphical interface is highly recommended for complex geometries where the “Plane of Incidence” might be difficult to visualize numerically. It ensures that the Gamma (polarization) angle is oriented exactly as intended relative to the physical orientation of your wires or surfaces.
