Hello Meep users, In a thread titled: "using perfect metal in C++ interface" ( http://www.mail-archive.com/meep-discuss@ab-initio.mit.edu/msg01997.html) Professor Johnson clarified that one controls the spatial location of the polarizability with sigma. However, both Renaud Vallee ( http://www.mail-archive.com/meep-discuss@ab-initio.mit.edu/msg03271.html) and Bin Huang ( http://www.mail-archive.com/meep-discuss@ab-initio.mit.edu/msg03784.html) have run into problems trying to implement multiple polarizations to describe a metal. I do not see a problem with Renaud's approach. Is he declaring his sigma functions appropriately? To specify multiple polarizations, is Renaud correct in applying the add_polarizability method to a structure object twice with different parameters?
Best, Eric
