Hi Sadovnikov, thanks for your answer! you can find the values I'm talking about here: http://ab-initio.mit.edu/wiki/index.php/Dielectric_materials_in_Meep
so my dimension unit is 1cm, so my freq unit is c/a=30GHz. from http://ab-initio.mit.edu/wiki/index.php/Dielectric_materials_in_Meep my parameters are: epsilon_inf = 6.75 sigma_n = 47.91 omega_n = 6E11 gamma_n = -3.6360e+12 so I set the parameters in meep as following: epsilon = epsilon_inf sigma = sigma_n omega = omega_n / (2pi) / 30e9 gamma = gamma_n / (2pi) / 30e9 can somebody please tell me if this is done correctly? I'd really appreciate it :) Have a nice weekend Matteo 2010/2/5 SadovnikovAV <leos...@mail.ru>: > Dear Matteo, > what is gamma? > I try to suppose that with omega and eps all is ok) > Sasha > -- Matteo Bassi E-mail: bassi.mat...@gmail.com _______________________________________________ meep-discuss mailing list meep-discuss@ab-initio.mit.edu http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
