Dear MPB users I am trying to obtain an E-field profile for the first y-odd gap band in a W1 waveguide in a triangular lattice hole slab structure. As you know, this mode has non-zero Ex,Ey and Hz.
I am using a modified version of the tri-holes.ctl file, which uses the basis vectors (basis1 (/ (sqrt 3) 2) 0.5) and (basis2 (/ (sqrt 3) 2) -0.5))). When I output the Hz field and run mpb-data to restore a rectangular cell, everything is OK. However, the fields appear skewed when I do the same for the E-fields and I'm not sure why this is the case. Can anyone shed some light on this issue please? Thanks Rikki Coles
