Thanks for your reply!
I took your advice to set the light source to a plane wave, but I didn't get the results I wanted. However, under the TFSF light source, the overall trend of my amplitude curve is somewhat similar, so I wonder whether he is the TFSF light source. If yes, then I extended the simulation time to 8000fs, and the result was that the energy was stable around 0.003 and did not decay. Do you still need to extend the simulation time?
Also, I would like to know how to decompose the monitor field into circular polarization?
Look forward to hearing from you and thank you in advance!
