We have a recent paper on one such "effective 2d" technique, which also
references other work on this:
http://www.opticsinfobase.org/oe/abstract.cfm?URI=oe-20-2-1617
However, I should note that all of these "effective 2d" techniques are only
heuristic approximations when applied to high-contrast 3d structures --
although they are often surprisingly effective, at least at predicting the
dispersion relation, there is no guarantee of accuracy. It isn't actually
that expensive to just do the full 3d calculation, so I usually recommend that
you do this at some point, although it is good to start with the 2d
calculations just because they are simpler and can give you a rough
understanding of what is going on before you deal with the complexities of 3d.
