[Meep-discuss] png visualisation

Hi meep users, There are two signals (same polarized) propagation in the waveguide simultaneously. They have different frequency but one of the amplitude is higher than the other one. So, higher amplitude field is dominant in the png image. How can I distinguish visualization of signals in png

[Meep-discuss] k scale

Hi meep users, I am trying to tilt my source. my source is located in the dielectric waveguide medium So when I set the k, should I use the refractive index of waveguide medium in to the wave vector scale definition as the following: (define-param kdir (vector3 1 -1)) (define k (vector3-scale

[Meep-discuss] I am a bit confused about nonlinearity

Dear meep users, I read the units and nonlinearity in meep wiki pages but I am a bit confused. I want to get delta_n=0.03. Therefore, following parameters are used in the ctl file.(my lattice constant a=1um) n2=10E-6 and related kerr parameter is chi(3)=7.053x10E-6 n=2.3 (linear index)

[Meep-discuss] after-time usage

Hi everyone, I want to get flux after the specific meep time later. I used the following command in my ctl file. But I could not see any difference between fluxes with and without (after-time TT..) command. I got the same fluxes. srcf=cw source frequency and start at the beginning, end time is

[Meep-discuss] field synchronization

Hi meep users, I have two sources in my structure. One of them is Ez field, the other one is Hz field. I want to get fluxes with add-flux function. In wiki page, fields are synchronized automatically in flux-in-box and field-energy-in-box routines. But I am using add-flux function to get fluxes.

[Meep-discuss] flux start time

Hi meep users, Is there any parameter or any way to define flux measurement start time-end time like source's? Pamukkale University Electrical-Electronics Eng.Dept. 20070 Kinikli-Denizli TURKEY Tel: (+90 258) 296 3213 ___ meep-discuss mailing list

Re: [Meep-discuss] About nonlinear transmission curves

Dear Dr. Steven, You suggest to use a CW source at each frequency and wait for the system to reach steady-state. What is the mean of systems steady-state How can I understand system is steady-state or not. I try to get transmission curves of nonlinear wg. I apply to cw input source at each

[Meep-discuss] flux delay

Hi meep users, Is there any parameter like source's start time-end time for flux measurement? For example, two sources which have different start time are applied to structure. I want to measure flux after the all sources beginning. Pamukkale University Electrical-Electronics Eng.Dept. 20070

[Meep-discuss] field profile along the axis

I want to get electric field intensity profile along the waveguide axis (for example each point in x direction ) How can I do? in meep reference, (get-field-point c pt) function is used for single point. I need field intensity-position graphs. Maybe, I should write script to get intensity at

[Meep-discuss] transmission ratio bigger than one

Hi meep users, I am trying to obtain transmission spectrum in order to see band gap like in the “Meep Tutorial/Band diagram, resonant modes, and transmission in a holey waveguide” example. I look at the waveguide output flux with and without periodic structures at same flux point and
