i'm looking for information that can help me analysis aperture-coupled microstrip antennas whose apertures are of arbitrary shapes. i want to use a hybrid of MoM and FEM fo the analysis. Does anyone have some information on this or where i can get them?

Well if as far as cpmmercially available softwares are concerned there are no commercial softwares, which make use of combination of MoM and FEM. There is ie3d which uses MoM and HFSS which uses FEM. You will have to develop ur own code for that purpose. Good Luck

hi kivet,

I think I can help you: http://www.feko.info/ They have (-the only I know) MOM/FEM hybrid and they have coupled also MOM with optic methods (PO/UTD) and the best: there is also a free Lite-Version!!
Hope this helps
