The propagation sweep tool automates the propagation for a range of cell group spans and collects
the user s matrix for each point in the sweep.
This is very useful for characterizing length-dependent transmission and reflection properties as
shown in My First Simulation section where we used it to get conversion efficiency as
a function of taper length.
Monitors do not record any results during the propagation sweep.
So, the propagation settings for error diagnostics and update monitors don't affect the sweep
speed or the results.
To set up the propagation sweep, first choose which group span to sweep from the "parameter"
dropdown menu.
Specify the range of group spans by setting the start and stop values.
Set the interval between sweep points, or the number of points in the sweep range.
Press the "eme sweep" button to run.
Once the sweep is done, use the "visualize eme sweep" button to plot the user s matrix.
The parameter sweep performs the propagation step for each sweep point.
However, the modes don't need to be re-calculated at each point, making it considerably fast.
For sweeping other parameters where modes need to be re-calculated for each point in the
sweep, use Optimizations and Sweeps tool.
