[Meep-discuss] Meep-discuss: Different field output when using output_hdf5 & get_field

2013-06-04 Thread Jakob helander
Hi everbody! I use the C++ version of Meep for analyzing the magnetic field in a ring resonator. I have been saving the data for the Hz field for every time step in the same location in two different ways, using the output_hdf5 & the get_field - command. while (f.time() < stop_time_unit) {

Dear Gholamhosain, the permittivity has to be established from experimental (or quantum-mechanical) sources, see for instance http://xplqa30.ieee.org/ielx5/5503869/6055237/6004802/html/img/6004802-fig-2-large.gif This graph may be easily converted to numerical data using Engauge or similar program

Hello, You do not need DL model to describe organic materials, they are described using regular dielectric permittivity (complex if you want to account for dielectric losses). You can determine them from the known refractive indices. For ITO it might be different, because it is conductive and in

*Hi all* I am interested in meep for organic solar cell. My problem is that I do not know the Drude-Lorentz parameter for regular organic materilas (PEDOT:PSS and PCBM:P3HT, ITO) Is there any program or code for finding Drude-Lorentz parameters from experimental data (for example e1 and e2( e=e
