Re: [Meep-discuss] Continuous time source and pulse

I'm getting a dirac-delta type pulse at the starting time of the source. I have code to run to see what is going on. Simulating for a longer time does allow for the initial pulse to fade sufficiently that there is only a small effect left. #include #include #include #include #include using na

Please, Can anyone answer me? I need the ansewer as soon as possible. ___ meep-discuss mailing list meep-discuss@ab-initio.mit.edu http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss

Re: [Meep-discuss] Continuous time source and pulse

Brian, what does the start-up pulse mean? Maybe you shoud increase your computational time in order to skip the transient process. Try to explain your problem more detailed in other case. Alexandr. ___ meep-discuss mailing list meep-discuss@ab-initio

Re: [Meep-discuss] Question about (run-k-point s...) and nonlinear material.

Thank you, Prof. Steven! I just tried to compute band gap diagram for 2d periodical structure, with nonlinear layers and then I want to compare this result with the results from the nonlinear Shroedinger equations. So I want to see how the cut-off frequencies changes with the amplitude gets la

[Meep-discuss] Continuous time source and pulse

When I run meep using the continuous time source I'm getting a large pulse when the source starts. Changing the start time and slowness factor does not decrease the start up pulse. Since I'm simulating 900MHz the pulse at the start is very undesirable for the simulation. Is there something I can do
