Hello Tisham

Nice to hear about this application.

Definitely, I suggest that you create a 2D numpy array with the
dielectrics. Then, you can create a callback class which inherits from
CallbackMatrix2D and interfaces this matrix with the Meep core.
See paragraph 3.3 of the python-meep documentation and related example
in the /samples directory (be sure to store a pointer to the numpy array
as local member variable, to avoid the 'segmentation fault' error : this
is also described in the documentation).

If you have any further questions, you can contact me or post on the
python-meep mailinglist (subscribe first through the launchpad page).
