Dear MEEP users, I am trying to figure out the decaying function of gaussian-src or continuous-src, and hope to hear your advice.
The default source end-time[] is infinity (never turn off) according to MEEP reference. And, the default cutoff[] is 3.0 and it is the number of widths the current decays for before we cut it off and set it to zero. Question (1) The question is how do the current decays when the source never turn off ? (2) I am guessing it is probably due to PML, but where in the geometry do MEEP consider the current to be decaying ? Thank you very much for helping me. -Chan Hoe-
