=== PO Sweep Simulations ===
[[Image:po_phys52.png|thumb|300px|EM.Illumina's Frequency Settings dialog.]]
You can run [[EM.Cube]]'s PO simulation engine in the sweep mode, whereby a parameter like frequency, plane wave incident angles or a user defined variable is varied over a specified range at predetermined samples. The output data are saved into data files for visualization and plotting. [[EM.Cube]]'s [[PO Module]] currently offers three types of sweep:
In a parametric sweep, one or more user defined [[variables]] are varied at the same time over their specified ranges. This creates a parametric space with the total number of samples equal to the product of the number of samples for each variable. The user defined [[variables]] are defined using [[EM.Cube]]'s '''[[Variables]] Dialog'''. For a description of [[EM.Cube]] [[variables]], please refer to the "Parametric Modeling, Sweep & [[Optimization]]" section of [[EM.Cube]] Manual or see the "Parametric Sweep" sections of the FDTD or [[Planar Module]] manuals.
