MPB only does one thing, and that is to compute harmonic modes (waveguide modes, band structures, etcetera). For transmission/reflection calculations, you need another tool (e.g. MEEP or CAMFR or SCUFF-EM or...) --SGJ PS. In some special cases, you can plug the harmonic modes computed by MPB into a semi-analytical method to compute reflections, e.g. coupled-wave theory in a slowly varying waveguide. But eigenmode-expansion methods to solve scattering problems in general cases (e.g. RCWA methods like CAMFR) require evanescent modes, which MPB does not (directly) compute. _______________________________________________ mpb-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/mpb-discuss
