Yes, in principle you should take the field pattern in a cross-section (or a unit cell for a periodic waveguide) and decompose it into the different modes by using the orthogonality relation. Meep doesn't have any built-in function to do this, however; you would have to do it yourself (e.g. by exporting the fields into Matlab, and also computing the eigenmodes in MPB and exporting those to Matlab, and then computing the appropriate E x H inner product.)
