== EM.Illumina's Excitation Sources ==
EM.Illumina provides three types of sources for the excitation of your physical optics simulation:

== Working with PO EM.Illumina's Simulation Data ==
EM.Illumina does not produce any output data on its own unless you define one or more observables for your simulation project. The primary output data in the Physical Optics method are the electric and magnetic surface current distributions on the surface of your structure. At the end of a PO simulation, EM.Illumina generates a number of output data files that contain all the computed simulation data. Once the current distributions are known, EM.Illumina can compute near-field distributions as well as far-field quantities such as radiation patterns and radar cross section (RCS).
