MPB problem: refraction of EM wave between two photonic crystals

Hi, MPB people,

I am studying the refraction of EM wave between two photonic crystals. 
In general, the refraction of light obeys Snell's law when light 
travels from one medium to another one. what about the refraction in 
phtonic crystal?

My first question is if MPB can apply in such a photonic crystal which 
is made up two same kind structures (for example, both of them are 
triangle structures) except the different lattice constant (for 
example, one structure has the lattice constant of a and another has 
1.2a.).

My second question is how to analysis the refraction propeties if MPB 
gives me the simulation results. For example, how to know bandwidth of 
refraction light from the band diagram? this question likes Q factor 
question in laser.

thanks,
