Dear Meep-users, I want to graph the normalized input and output time-pulse shapes (Hz field) in a photonic crystal waveguide in dielectric background. I place two detectors, one a little far from source (5a) and the second is at the end of the waveguide.I sent a Gaussian pulse with a very narrow (etc. 0.001(lambda/a)) bandwidth.
1-) Does the position of the input detector affect the resulted field amplitude of the output detector ? I suppose that reflection can occur from the input detector which may distort the output pulse shape. 2-) To stop the run earlier I give bigger decay-by values ( etc 0.9 here: (stop-when-fields-decayed 50 Hz (vector3 (- (/ sx 2) dpml 2) 0) 9e-1) ). However, the computation continues although field decay value is smaller ( etc: field decay(t = 850.233333333333): 7.57237831641646e-13 / 1.22004831934991e-11 = 0.06). I would like to stop the run whenever I want in order to examine the pulse field amplitude and shape. How can I do that? I would very much appreciate your answers and suggestions regarding my questions. Best, Fulya Bagci Ankara University Department of Engineering Physics
