Version Veröffentlicht Versionshinweise
3.0.0

PPML 3.0 now includes the possibility to model purely 2-dimensional conducting interfaces (i.e., graphene, ...) by means of a local conductivity model. Ordinary dielectric and metal structures can be always modeled, as well as hybrid ones.

2.1.0

New version of ZSM_2d_rect.m, now calculates rectangular hole in rectangular lattice.

Fixed an error in field normalization, file \1d\epar_1d.m. It affected only non-normal incidence.
