[Meep-discuss] How to obtain the flux spectra at single frequency by using loop structure

Dear all meep users,       I got a question about the flux calculation. Now, I want to obtain the transmittance spectra of 2d photonic crystals. As we know, we could use the (add-flux ()) to achieve it. However, I want to calculate it at every single frequency. I wrote a ctl file about

[Meep-discuss] Transmittance curves simulation.

Dear Mr.steven and all users:   I want to caculate the transmittance curves of a photonic crystals slab, which is made of nonlinear medium. i knew how to caculate transmittance curves for linear medium like as the example in the meep tutorial (holey-wvg-cavity.ctl ). In pervious

Dear Mr. steven:      I want to add kerr nonliear in my simulation and caculate the transmittance curve. For example, the nonliear index (experiment data) n2=0.0435um^2/W, if i want to get the changing of the index n2*I with  order of 1e-3, we should use pump intensity of   0.02299 W/um^2.
