Hello MPB Users and Steven,
I'm currently trying to calculate the photonic band structure of a
monoclinic lattice. Unlike FCC, the BZ shape can change a lot depending on
the lattice constants and there are less equivalent points. I've been able
to determine all the critical points on the BZ as shown in the picture link
below:

I'm trying now to determine the k-points I would have to interpolate.
For example, I know I would have the interpolate points betwen A to B and B
to C, or G to J or S to M. However, would I also need to interpolate
between, say, E and G or D and K (i..e diagonal across faces and the like)?
I'm trying to look for general principles to choose all the points
necessary (minimizing redundancies and unneccessary points) for which to do
calcuations to create my band structure.
Any help would be much appreciated!
Thanks,
Ian
