Currently there is no direct indicator of uniformity in this module, you can try to use the averaging operator in non-local coupling combined with mathematical calculations to get values similar to RMS, Var. For the setting of circular polarization, you can refer to this thread in the forum: https://www.comsol.com/forum/thread/296571/how-to-generate-linear-polarized-light-and-circular-polarized-light-in-comsol

And how to achieve circular polarization excitation?
