As I understand it, Ryan wants to calculate the transmission through a finite number of periods in the Y direction. Hence he needs to use PML in the Y direction too. > In summary, PML in Z direction, periodicity in X and Y. (Technically, the PML directions are also periodic. It's just that the periodicity in those directions is irrelevant, as I explained in my previous message.) _______________________________________________ meep-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
