If you want a planewave, I would use a planewave (which for normal incidence is
just a constant current plane). To control the polarization, just add two
sources, one Ex and one Ey, and set whatever relative amplitudes you want.
(For example, for circularly polarized light, make the Ey amplitude ±i.)
