-The total emitted power obtained from the LDOS terms of the formula above must be multiplied by $\Delta V$, the volume of the voxel. In cylindrical coordinates, $\Delta V = \Delta r \times \Delta z \times 2 \pi r$. Meep implements an $r = 0$ source at $r = 0.5 \Delta r$, corresponding to the smallest-$r$ $E_r$ Yee grid point. This means that for a source at $r = 0$, $\Delta V = \pi / resolution^3$ since $\Delta r = \Delta z = 1 / resolution$. In 3D, $\Delta V = \Delta x \times \Delta y \times \Delta z = 1 / resolution^3$ for every voxel in the cell.

 As shown in the figure below, the results from the two coordinate systems have good agreement.
