'dxes' datastructure which contains grid cell width information in the following format:
|

[[[dx_e_0, dx_e_1, ...], [dy_e_0, ...], [dz_e_0, ...]],
|
|
[[dx_h_0, dx_h_1, ...], [dy_h_0, ...], [dz_h_0, ...]]]

where dx_e_0 is the x-width of the x=0 cells, as used when calculating dE/dx,
|

and dy_h_0 is the y-width of the y=0 cells, as used when calculating dH/dy, etc.
