Dear meep users, I met a strange thing when I was trying to get transmission spectrum of nonlinear waveguide.
method is applied according to the the following topic: http://thread.gmane.org/gmane.comp.science.electromagnetism.meep.general/2008/focus=2052 Single source frequency continuous wave source is applied to the medium and than get flux value for this single source frequency as ;; srcf is source frequency for example 0.6 (define transout (add-flux srcf 0 1 (make flux-region (center flxout 0) (size 0 flxsize) ) ) ) This give me a one flux value at selected single source frequency.then this calculation is iterated for each frequency in normalized spectrum. its ok. When I use the different flux region (below) with wide frequency but all the values remain the same before (single source frequency etc.), I get the different peak value at this single source frequency. (define transout (add-flux srcf 1 500 ;; srcf= flux center freq. 1=df, 500=N (make flux-region (center flxout 0) (size 0 flxsize) ) ) ) What is the different of flux-region calculation? Which one is correct for nonlinear transmission curves? Best... Onder
