For details of source implementation you can refer a FDTD book, or Shineider's online book.

where did you get the simulated result? from source its self or from a monitor? where the monitor is located? I did not find more information how did you import and how did you measure it.


I tested a plane wave import without noticing any additional phase from the source.

simply modify this examle




and set the xy boundary conditions as periodic. Please test your own and compare with your original simulation.
