3DTo2D¶

Type:: enum
Range:: no, yes
Default:: no

Activating this parameter applies a final rotation on the defined plane wave which interchanges the coordinates

$\begin{eqnarray*} z & \rightarrow & y \\ y & \rightarrow & -z \end{eqnarray*}$

This helps to conveniently change the coordinate system from an originally 3D setup with $z$ being the optical axis to match the $xy$ -coordinate plane convention of a 2D simulation.
