There currently isn't any way to output the dielectric tensor directly. The best thing to do, if you are worried about orthonormality relations, is to compute the relevant dot products from within Meep using its field integration routines. The second best thing to do is to output both E and D. However, realize that the output .hdf5 files are linearly interpolated from the Yee grid onto a single voxel-centered grid, so this is not quite the same thing (especially near boundaries where the fields are discontinuous).
