Below is a simple test to view the z-component of the H field and magnetic energy density in a triangular lattice of air-holes. I have attached the pics for the first and second band. This looks a bit odd, should the field antinodes not be located in the dielectric for the first band? it almost looks like the opposite of what we would expect (first and second band). I am sure this must have been discussed elsewhere but couldn't find this particular topic.
Looks right to me. Remember, the variational principle tells you that the *electric* field energy tries to be concentrated in the high dielectric for the lowest bands, not the *magnetic* field energy.
