Hi Julia,
If you are interested in propagation in the presence of weak
nonlinearity then you can do it perturbatively based on linear band
structure calculations with MPB. This involves mode overlap integrals
using the function |(integrate-fields ...)|. For example this sort of
thing is done in Phys. Rev. E *69*, 016604 (2004) and Physical Review E
*64*, 056604 (2001).
Cheers,
Navin

Hello!
I've just started using the MIT PBG programme and I am wondering if
there is any chance to include nonlinear materials in the calculations.
Thank you very much!
Julia
