Claryfing units for TFSF source.

[FilipeFcp]

The documentation of the TFSF says that the source injects $1W/um^2$ of power, but the units are in Intensity, not power, right? So seems that the intensity is constant, but the Power varies with the source size, am I correct?

I had to get the $|E|^2$ and got a bit confused if I should multiply by the source area or not. Maybe would be interesting to clarify that according to the Poyting theorem. $I = (1/2)c n \epsilon_0 |E_0|^2 = 1$.
