Re: [Meep-discuss] Integrate CW fields in a finite plane

Dear Yongsop Hwang, Seems it is quite physical the oscillating of E and H and have similarity with Fresnel zones. But it is not for Sx (by the way - you may use sx as you use ex, ey, hz, http:// jdj.mit.edu/wiki/index.php/Meep_Reference#Constants_.28enumerated_types.29 ). You should be carefull wit

[Meep-discuss] Integrate CW fields in a finite plane

Dear Steven and all meep users, My question is this. Q: Why do the integration of CW fields depend on the frequency? It's a 2D FDTD calculation in xy-plane. I've launched a CW source of Hz polarization at a certain point, and integrated Ex, Ey, Hz fields and the Poynting vector Sx on a certain yz

Sasha, If you are interested to using the Python interface to Meep, then take a look at the example at the end of paragraph 5 in the documentation which you can find here : http://claudia.intec.ugent.be/software/python-meep/python_meep_documentation.html Look for the example under the sentence "He

Thank you a lot, Emmanuel! Now I'm not using the Python Interface for doing the calculations with meep, however if there is'n another way (e.g. in the ctl file with the facilities of scheme language) I will study the possibility to use python interface you have write about. I suppose, there is a p

Dear Mischa, you suggest Kadir to use the shape of the mode he desire as the spatial amplitude for an extended source. I've read the meep-tutor and study some examples of meep's ctl file and I haven't find the proper way to set the spacial distribution of field (of source exactly) for example i
